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 &#x3bc;m or less. The resin composition includes particles of the (B) fluorine series resin having particle diameters of 0.8 &#x3bc;m or greater. The percentage of particles having particle diameters of 0.8 &#x3bc;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.
