Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a resin welding method capable of reliably preventing the occurrence of damage due to excessive heat input in a planned welding region.SOLUTION: In this resin welding method for manufacturing a resin welded body by welding a first resin member to a second resin member, a laser beam where light intensity at a center part is set lower than that in a circumferential part at least at an end on a laser beam incidence side of a planned welding region is emitted to converge in the planned welding region between the first resin member and the second resin member; and the emission position of the laser beam is relatively moved along the planned welding region to melt the first resin member and the second resin member in the planned welding region.
