Abstract
A composite molded article obtained by laser welding molded article composed of a polyester resin composition having a crystallinity of 15% or more as calculated with fast scanning calorimetry by a calculation method, wherein the calculation method includes using fast scanning calorimetry, the polyester resin composition is heated from 30° C. to 260° C. at 10000° C./second, then maintained at 260° C. for 0.1 second, then cooled to 80° C. at 5000° C./second, maintained at 80° C. for 0.1 second, then cooled to −70° C. at 5000° C./second, and then heated to 260° C. at 1000° C./second, after which the curve obtained is used to calculate the crystallinity.
