Provide is a polyamide resin that can yield a molded article with good appearance and good solder reflowability, while keeping low water absorption rate; a molded article; and a method for manufacturing a polyamide resin. The polyamide resin, which is composed of a structural unit derived from diamine and a structural unit derived from dicarboxylic acid; 70 mol% or more of the structural unit derived from diamine being derived from 1,4-bis(aminomethyl)cyclohexane, 1,4-bis(aminomethyl)cyclohexane having a molar ratio (cis:trans) of 35:65 to 0:100, 70 mol% or more of the structural unit derived from dicarboxylic acid being derived from a straight chain aliphatic α,ω-dicarboxylic acid having 8 to 12 carbon atoms, the polyamide resin containing 20 to 100 ppm by mass of phosphorus atom, and containing calcium atom so that the molar ratio given by (phosphorus atom):(calcium atom) will be 1:0.3 to 0.7.
