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, a glass transition point (Tg) is 333-363 K (60-90°C), and a ratio of the glass transition point (Tg) to a melting point (Tm) satisfies (formula 1): 0.600≤(Tg/Tm)≤0.650, wherein Tg and Tm are each an absolute temperature (K).
