Abstract: A resin composition may suppress color fading after a weathering test and excel in heat resistance. A formed article may use of such resin composition, as may a kit, a car-borne camera component, a car-borne camera module. A resin composition may include: per 100 parts by mass of a resin component that contains 50 to 95% by mass of a polybutylene terephthalate resin (A), and 5 to 50% by mass of a thermoplastic resin (B) that demonstrates a glass transition temperature, measured with use of a differential scanning calorimeter, higher by 15 to 150° C. than that of the polybutylene terephthalate resin (A); 0.001 to 5 parts by mass of a dye; and 5 to 100 parts by mass of an inorganic filler.

Abstract: Regarding a laser welded body in which a laser transmissive/absorptive molding member containing a PBT-based material and a laser absorptive molding member containing a PBT-based material are integrated with each other by laser welding, the following laser welded body is proposed as a laser welded body in which a bond strength can be further increased. A laser welded body having a structure in which a member I and a member II are integrally bonded to each other, the member I contains 0.0005 to 5.0 parts by mass, with respect to 100 parts by mass of a polyester-based resin A, of a laser transmissive/absorptive coloring material capable of transmitting and absorbing laser beam, and the polyester-based resin A contains at least a polybutylene terephthalate copolymer resin, the member II contains 0.15 to 10.00 parts by mass, with respect to 100 parts by mass of a polyester-based resin B, of a laser absorptive coloring material not transmitting but capable of absorbing laser beam, and the polyester-based resin B contains (B1) a homo PBT, (B2) a homo PBT-based mixed resin containing a homo PBT, or (B3) a copolymerized PBT-based mixed resin containing a copolymerized PBT.
