摘要:
A method of manufacturing a spark plug includes a joining step of joining a first member and a second member which constitute the spark plug. In the joining step, a first welding electrode in contact with the first member and a second welding electrode which has an elastically deformable intermediate portion and which is in contact with the second member are electrically connected through the first member and the second member, whereby the first member and the second member are joined together by resistance welding.
