Abstract

(Summary) In the present invention, a first resin member 2 and a second resin member 3 are welded by a laser light irradiation in a state in which the first resin member 2 and the second resin member 3 are compressed. The first resin member 2 is a light-absorbing resin member that absorbs laser light, and the second resin member 3 is a light-transmitting resin member that transmits laser light. A lower-side inclined surface 31 that is inclined with respect to a compression direction is formed on the second resin member 3, and a facing surface 21 that faces the lower-side inclined surface 31 and that comes into contact with the lower-side inclined surface 31 due to compression is formed on the first resin member 2. In a welding step, the first resin member 2 and the second resin member 3 are welded by having laser light transmit through the second resin member 3 from a direction intersecting the compression direction and irradiate a contact part 53 that is between the lower-side inclined surface 31 and the facing surface 21. In this process of the welding, the contact area between the lower-side inclined surface 31 and the facing surface 21 expands through having the first resin member 2 heated and softened at a portion irradiated with the laser light.
