A polyamide resin composition contains a polyamide resin and an inorganic filler. 90 mass % or more of polyamide 66 is contained relative to 100 mass % of the polyamide resin. The inorganic filler content is ≥30 mass % relative to 100 mass % of the composition. The composition has a solidifying point of ≥210° C. The composition has a spiral flow value of ≥60 cm when the inorganic filler content is ≥30 mass % and <40 mass %, ≥40 cm when the content is ≥40 mass % and ≤50 mass %, and ≥20 cm when the content is >50 mass % and ≤70 mass %. The composition has a strain of ≤3.8% in a 1000-hour tensile creep test under 120° C. and 60 MPa. The composition has a formic acid relative viscosity (VR) of 30
