摘要

The present invention relates to a polyamide resin comprising a unit derived from µ-caprolactam and/or µ-aminocaproic acid (to also be referred to as "Unit 1 "), a unit derived from adipic acid (to also be referred to as "Unit 2") and a unit derived from hexamethylenediamine (to also be referred to as "Unit 3"), wherein the concentration of terminal amino groups in the polyamide resin is greater than the concentration of terminal carboxyl groups in the polyamide resin, and the amount of Unit 1 is greater than 60% by weight to less than 80% by weight of the total amount of Unit 1, Unit 2 and Unit 3.
