1. A method for producing a resin pellet comprising:
preparing a resin base material; embedding a plurality of microparticles in said resin base material by dispersing, in a liquid comprising water, said resin base material in a softened state and said microparticles; and drying the resin base material in which the plurality of microparticles are embedded, to remove the liquid comprising the water, wherein, a shore hardness of said microparticles is higher than a shore hardness of said resin base material, the shore hardness being measured according to JIS K7215, a degree of crystallinity of said microparticles is higher than a degree of crystallinity of said resin base material, the degree of crystallinity being measured by an X-ray diffraction method, a Vicat softening point of said microparticles is higher than a Vicat softening point of said resin base material, the Vicat softening point being measured according to JIS K7206, said resin base material contains an ethylene-vinyl acetate copolymer, a content of vinyl acetate in said ethylene-vinyl acetate copolymer contained in said resin base material is 20 to 50 mass %, said microparticles contain an ethylene-vinyl acetate copolymer, a content of vinyl acetate in said ethylene-vinyl acetate copolymer contained in said microparticles is 5 to 20 mass %, and in embedding said plurality of microparticles in said resin base material, the surface of said resin base material is covered with said plurality of microparticles. |
