Abstract
A polyamide resin composed of constitutional units derived from a diamine component 70 mol % or more of which is derived from p-xylylenediamine and constitutional unit derived from a dicarboxylic acid 70 mol % or more of which is derived from an aliphatic dicarboxylic acid having 6 to 18 carbon atoms. The polyamide resin has a number average molecular weight (Mn) of 10,000 to 50,000 and a degree of dispersion (weight average molecular weight/number average molecular weight=Mw/Mn) satisfying the following formula (1):1.5≦(Mw/Mn)≦6.0,wherein Mw and Mn are determined by gel permeation chromatography (GPC).
