1 . An element, comprising:
 a first electrode;   an intermediate layer; and   a second electrode,   the first electrode, the intermediate layer, and the second electrode being laminated in this order,   wherein the intermediate layer has flexibility,   wherein the intermediate layer has a single layer structure, and   wherein a deformation amount on the side of the first electrode of the intermediate layer is different from a deformation amount on the side of the second electrode of the intermediate layer when a pressure is applied to the intermediate layer in a direction orthogonal to a surface of the intermediate layer.   
     
     
         2 . The element according to  claim 1 , wherein a universal hardness (H1) at an indentation depth of 10 μm on a side of the first electrode of the intermediate layer is different from a universal hardness (H2) at an indentation depth of 10 μm on a side of the second electrode of the intermediate layer. 
     
     
         3 . The element according to  claim 2 , wherein a ratio of the universal hardness (H1) to the universal hardness (H2) (H1/H2) is 1.01 or more. 
     
     
         4 . The element according to  claim 1 , wherein the intermediate layer comprises polyorganosiloxane comprising a silicon atom bound to 3 to 4 oxygen atoms.
