Abstract

Provided is a semi-aromatic polyamide resin having a diamine unit and a dicarboxylic acid unit, in which the diamine unit contains 60 to 100 mol% of an aliphatic diamine unit having 7 to 13 carbon atoms with respect to 100 mol% of the diamine unit, the dicarboxylic acid unit contains 60 to 100 mol% of an aromatic dicarboxylic acid unit with respect to 100 mol% of the carboxylic acid unit, an inherent viscosity η<inh> measured at 30°C in concentrated sulfuric acid is 1.6 to 3.0 dL/g, an amount of terminal amino groups [NH<2>] is 10 to 70 microequivalent/g, an amount of terminal carboxy groups [COOH] is 10 to 90 microequivalent/g, and a ratio of the amount of terminal amino groups [NH<2>] to the amount of terminal carboxy groups [COOH], [NH<2>]/[COOH], is 0.1 or more and less than 1.0.
