Abstract
The present invention provides a joining method using a method of laser welding wherein two resin molded bodies can be joined with high welding strength. Specifically, this is a method that joins two thermoplastic resin molded bodies using a method of laser welding; the first resin molded body is a laser light transmissive molded body comprising a thermoplastic resin and cellulose fibers with an α-cellulose content of 80% or more; the second resin molded body is a laser light absorbent molded body containing a thermoplastic resin and a colorant; and the first resin molded body and the second resin molded body are welded by irradiating laser light from the first resin molded body side.
