Provided are a novel polyamide resin having a high melting point, and a composition and a molded article, for which the novel polyamide resin is used. A polyamide resin including a constituent unit derived from a diamine and a constituent unit derived from a dicarboxylic acid, where 70 mol % or more of the constituent unit derived from the diamine is derived from a xylylenediamine; and 70 mol % or more of the constituent unit derived from the dicarboxylic acid is derived from a phenylenediacetic acid; and where X+(Y/3) is 68 or more, when X mol % is defined as a proportion of a constituent unit derived from 1,4-phenylenediacetic acid in the constituent unit derived from the dicarboxylic acid, and Y mol % is defined as a proportion of a constituent unit derived from p-xylylenediamine in the constituent unit derived from the diamine.
A polyamide resin comprising a constituent unit derived from a diamine and a constituent unit derived from a dicarboxylic acid,
A polyamide resin comprising a constituent unit derived from a diamine and a constituent unit derived from a dicarboxylic acid, wherein more than 50 mol % of the constituent unit derived from the dicarboxylic acid is derived from 1,4-phenylenediacetic acid.
