Abstract:
1. A polyamide resin, comprising: a constitutional unit derived from diamine component, and a constitutional unit derived from dicarboxylic acid component, wherein 70 mol % or more of the constitutional unit derived from the diamine component is derived from p-xylylenediamine, 70 mol % or more of the constitutional unit derived from dicarboxylic acid component is derived from an aliphatic dicarboxylic acid having 6 to 10 carbon atoms, a number average molecular weight (Mn) is from 10,000 to 50,000, and a degree of dispersion expressed by Mw/Mn=weight average molecular weight/number average molecular weight satisfies formula (1) wherein Mn and Mw are determined by a gel permeation chromatography (GPC).
