Abstract
This polyamide resin composition contains: 30-89.9 parts by mass of a polyamide resin (A) having a melting point of at least 300° C.; 0-45 parts by mass of a polyamide resin (B) having substantially no melting point; 0.1-5 parts by mass of a light-transmitting pigment (C); and 10-55 parts by mass of a fibrous filler (D) (the total amount of (A), (B), (C), and (D) is 100 parts by mass). The polyamide resin (A) contains at least a terephthalic acid-derived component unit. In a molded body of the polyamide resin composition, the corrected heat of fusion (ΔHR) is 10-70 J/g, and the transmittance of laser light having a wavelength of 940 nm is at least 15% at a thickness of 1.6 mm.
