         2 . The warming tool according to  claim 1 , wherein
 the neck part is linearly formed between the upper end parts of the front face part and the back face part.   
     
     
         3 . The warming tool according to  claim 1 , further comprising sleeve parts connected to the arm parts and having a tubular shape so as to cover sections of the arms of the human body that protrude from the arm parts. 
     
     
         4 . The warming tool according to  claim 1 , having dimensions that, when worn on a human body of a standard type (presumably about 170 cm in height and about 60 kg in weight), allow at least both knees of the human body to be covered. 
     
     
         5 . The warming tool according to  claim 1 , wherein
 the plurality of pockets is formed only on the surface of the front face part and not on the back face part.   
     
     
         6 . The warming tool according to  claim 1 , wherein
 the plurality of pockets includes at least one of the following:   (1) a pocket formed for disposing the heating element in a vicinity of an armpit of the human body;   (2) a pocket formed for disposing the heating element in a vicinity from a groin region to a femoral region of the human body; and   (3) a pocket formed for disposing the heating element in a vicinity of an abdominal region of the human body where bones do not exist.   
     
     
         7 . The warming tool according to  claim 1 , wherein
 the plurality of pockets includes a pocket formed for disposing the heating element in a vicinity of a middle of a chest of the human body.   
     
     
         8 . The warming tool according to  claim 1 , wherein
 the front face part further comprises a hole for promoting intake of heat from the heating element into the warming tool, in each pocket forming position.   
     
     
         9 . The warming tool according to  claim 1 , wherein:
 the pocket comprises an upper side fabric piece and a lower side fabric piece;   the upper side fabric piece comprising a peripheral edge section connected to the surface of the front face part, excluding a lower end side;   the lower side fabric piece comprising a peripheral edge section connected to the surface of the front face part, excluding an upper end side; and   the pocket being formed so that a lower side end part of the upper side fabric piece overlaps with an upper side end part of the lower side fabric piece, the heating element can be inserted and removed through this overlapping part, and the heating element is prevented from falling out of the pocket.   
     
     
         10 . The warming tool according to  claim 1 , wherein
 the flexible fabric is made of a nonwoven fabric that contains calcium carbonate and polypropylene.   
     
     
         11 . The warming tool according to  claim 1 , wherein
 the flexible fabric has a warm color such as yellow or orange.   
     
     
         12 . A warming kit, comprising:
 the warming tool according to  claim 1  that stores heating elements in pockets; and   a bag that stores the warming tool folded to a predetermined size;   the warming tool being vacuum-packed by the bag to prevent the heating elements from emitting heat.   
     
     
         13 . The warming kit according to  claim 12 , further comprising a cord member that is stored inside the bag and is for securing the warming tool worn on a human body to the human body. 
     
     
         14 . A method for manufacturing a warming kit, comprising the steps of:
 removing heating elements vacuum-packed in advance from a bag;   inserting the heating elements into the pockets of the warming tool according to  claim 1 ;   folding the warming tool to a predetermined size, and storing the folded warming tool in a bag;   vacuum-drawing the air inside the bag; and   sealing an opening of the bag.   
     
     
         15 . A warming method, comprising the steps of tearing the bag of the warming kit according to  claim 12 , pulling the warming tool of the warming kit over a head of a human body, passing the head through the neck part, and passing arms of the human body through the arm parts while causing the heating elements inside the pockets to emit heat, thereby warming the human body. 
     
     
         16 . The warming method according to  claim 15 , further comprising the step of binding the human body wearing the warming tool from an outer side of the warming tool using the cord member inside the bag of the warming kit according to  claim 13 , thereby preventing air warmed inside the warming tool from escaping to the outside.
