Abstract:
A resin molded product whose main component consists of an ethylene-vinyl acetate copolymer resin and carbon black. The ethylene-vinyl acetate copolymer resin has an MFR of 0.5 g/10 min or more and 20 g/10 min or less. The carbon black has an average primary particle diameter of 55 nm or more and 100 nm or less and a DBP oil absorption amount of 100 mL/100 g or more and 300 mL/100 g or less. The content of vinyl acetate is 2.9 parts by mass or more and 12.3 parts by mass or less based on 100 parts by mass of the main component. The resin molded product has a surface resistivity of 720 Ω/□ or less.
