Claim Text:
1. A polyamide resin molding, comprising: a polyamide resin comprising a diamine structural unit and a dicarboxylic acid structural unit or a polyamide resin composition including the polyamide resin, wherein 70 mol % or more of the diamine structural unit is derived from xylylenediamine and 50 mol % or more of the dicarboxylic acid structural unit is derived from sebacic acid, the polyamide resin molding has a crystallinity index of 0 to 50% and a moisture content of 0.1 to 2% by mass, and the xylylenediamine is a mixture of m-xylylenediamine and p-xylylenediamine, wherein the crystallinity index is determined by formula: where Qm is a heat of fusion of the polyamide resin molding, and Qc is a heat of crystallization of the polyamide resin molding during heating.
