A resin member includes a base material and a resin molded body disposed on the base material, the resin molded body containing a main component constituted by an ethylene-vinyl acetate copolymer resin and a carbon black. The resin molded body has two or more peaks within a range of 25° C. to 80° C. in an endothermic curve obtained through measurement performed by heating from 25° C. to 150° C. at 5° C./min with a differential scanning calorimetry (DSC) apparatus.
