RESIN COMPOSITION FOR LASER WELDING, MOLDED PRODUCT, COMPOSITE MOLDED PRODUCT AND METHOD FOR PRODUCING SAME, AND METHOD FOR IMPROVING LASER LIGHT TRANSMISSIVITY

摘要

[Problem] To provide a polybutylene therephthalate resin composition for laser welding, and a molded product. [Solution] To provide a polybutylene terephthalate resin composition for laser welding, containing: a polybutylene terephthalate resin; and a laser light transmissivity improving agent including a layered silicate mineral having an average primary particle size of 1.0 µm to 5.0 µm. The amount of laser light transmissivity improving agent contained is preferably 0.01 parts by mass to 20 parts by mass with respect to 100 parts by mass of polybutylene terephthalate resin.
