         8 . The button product manufacturing device according to  claim 5 , wherein
 a dynamic friction coefficient between the lower die and the spacer is 0.3 or more and 0.5 or less.   
     
     
         9 . The button product manufacturing device according to  claim 5 , wherein
 the die set further includes a back member lower die to which the back member is configured to be fed, and   the die set is configured to connect the back member supported by the back member lower die and the front member held by the upper die and provided with the spacer.   
     
     
         10 . The front member according to  claim 1 , configured to be used in a button product manufacturing device, the button product manufacturing device manufactures a button product by connecting the front member and a back member, the button product manufacturing device includes: a die set including: a lower die configured to support the front member; and an upper die configured to separate the front member from the lower die, and a front member feeder accommodating a plurality of the front members in a stacked state and configured to feed the front member to the lower die, wherein
 the front member is configured to be accommodated in the front member feeder.   
     
     
         11 . The front member according to  claim 1 , configured to be used in a button product manufacturing device, the button product manufacturing device manufactures a button product by connecting the front member and a back member, the button product manufacturing device includes: a die set including: a lower die configured to support the front member; and an upper die configured to separate the front member from the lower die, and a front member feeder accommodating a plurality of the front members in a stacked state, configured to feed the front member to the lower die, and the front member feeder having a front member slope configured to guide the front member toward the lower die, wherein
 the front member is configured to be guided to the front member slope.   
     
     
         12 . The front member according to  claim 1 , configured to be used in a button product manufacturing device, the button product manufacturing device manufactures a button product by connecting the front member and a back member, the button product manufacturing device includes: a die set including: a lower die configured to support the front member; and an upper die configured to separate the front member from the lower die, and a front member feeder accommodating a plurality of the front members in a stacked state, configured to feed the front member to the lower die, and the front member feeder including support portions provided on both sides in a direction intersecting a feed direction of the front member to the lower die, and an escape groove located between one support portion and the other support portion of the support portions and lower than the support portions, the front member feeder being a front member slope that is configured to guide the front member toward the lower die, wherein
