  • Patent number: 10767046
    Abstract: A polyamide resin molded body is formed by a resin composition having a (B) fluorine series resin within a range from 1 to 15 parts by mass with respect to 100 parts by mass of a (A) polyamide resin. In the resin composition, the number average particle diameter of the fluorine series resin dispersed in the polyamide resin is 0.8 ?m or less. The resin composition includes particles of the (B) fluorine series resin having particle diameters of 0.8 ?m or greater. The percentage of particles having particle diameters of 0.8 ?m or greater which are secondary particles while maintaining the form of primary particles is 60% or greater, and/or the degree of crystallinity of the dispersed (B) fluorine series resin is 42 J/g or greater.
