Abstract
The present invention is a polyamide resin (A) that contains from 95 to 99.95% by mass of a polyamide (a-1) having a number-average molecular weight of 2000 or more and from 0.05 to 5% by mass of a polyamide oligomer (a-2) having a number-average molecular weight of from 500 to less than 2000, in which at least 25 mol % of all the monomer units constituting the polyamide (a-1) and the polyamide oligomer (a-2) are structural units derived from a specific alicyclic monomer, and the content ratio of the trans isomer structural units derived from the alicyclic monomer is from 50 to 85 mol %. The polyamide resin (A) is excellent in heat resistance, low water absorption, high-temperature rigidity, chemical resistance and flowability, and exhibits the effects of securing sufficient crystallization even when molded in a mold at 80° C. and causing minimal mold deposit during production.
