A joining method of a resin member, the method comprising:
- laminating a first resin member and a second resin member both made of thermoplastic-resin material that absorbs light;
- forming a hole or a concave portion in the second resin member;
- arranging in the hole or the concave portion an optically transparent member that transmits light;
- and
- welding the first resin member and the second resin member by radiating light onto the first resin member side via the optically transparent member and fusing the thermoplastic-resin material of the first resin member and the second resin member at a welding region.
