Beschreibung
Zusammenfassung:	A welding method heats and pressurizes a contacting portion, where a first member and a second member made of resin are in contact with each other, by a pressing tool. The welding method has forming a step, forming a recessed portion, crushing a protrusion, and filling the recessed portion. The step is defined between the first member and the second member by providing the protrusion to the first member. The recessed portion is provided in a tip of the pressing tool. The protrusion of the first member is crushed in the recessed portion by being pressed toward the second member using the pressing tool. The recessed portion is filled with the molten portion of the first member and the molten portion of the second member such that a rim of an outer periphery of the recessed portion is dug into the first member and the second member.
