PROBLEM TO BE SOLVED: To provide a polyamide resin having excellent processability, high heat-resistance, low water-absorption property, chemical-resistance, excellent mechanical performance, and the like. SOLUTION: In the polyamide resin, 70 mol% or more of a structural unit derived from a diamine component is derived from para-xylylenediamine, and 70 mol% or more of a structural unit derived from a dicarboxylic acid component is derived from a 6-18C aliphatic dicarboxylic acid. In the polyamide resin, a fusion calorific value in measurement of a differential scanning calorimeter (DSC) is 60 J/g or higher and temperature difference of a reduction temperature crystallization temperature (Tcc) and a melting point (Tm) is in a range of (formula 1): 20≤(Tm-Tcc)≤40.
