A method of manufacturing a resin-made joint boot ( 10 ) provided with a boot body ( 12 ) including a large-diameter tubular part ( 14 ), a small-diameter tubular part ( 16 ) and a bellows section ( 18 ), and a bushing ( 30 ) fitted inside the large-diameter tubular part, wherein the boot body and the bushing are separately molded, the bushing is positioned inside the large-diameter tubular part of the boot body, and then, both are integrally fastened by laser welding. The large-diameter tubular part ( 14 ) is provided on its internal periphery with an outwardly divergent tilting surface ( 24 ) while the bushing ( 30 ) is provided with an annular projecting portion ( 42 ) to be abuttingly disposed on the tilting surface, and laser (R) is irradiated, penetrating through the annular projecting portion ( 42 ) onto the tilting surface ( 24 ). |
