Abstract

(Problem) To provide: a welding method with which laser welding can be reliably performed while limiting an increase in size; a resin joint; and a polygonal case. (Solution) A first resin member 2 and a second resin member 3 are welded by irradiation with laser light while the first resin member 2 and the second resin member 3 are under pressure. 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. The second resin member 3 is formed to have a lower side inclined surface 31 inclined with respect to a direction of pressure, and the first resin member 2 is formed to have a facing surface 21 facing the lower side inclined surface 31 and coming into contact with the lower side inclined surface 31 due to the pressure. In a welding step, the first resin member 2 and the second resin member 3 are welded together through irradiation with laser light by directing the laser light to a contact site 53 between the lower side inclined surface 31 and the facing surface 21 from a direction intersecting the direction of pressure so that the laser light passes through the second resin member 3.
