[Problem] In joining conductors by resistance welding, a resistance welding device and a resistance welding method capable of determining a joining quality, and a shape of a projection appropriate for determination of the joining quality, and used for the projection welding are provided, and their electrical reliability and mechanical joining strength are improved by using the resistance welding device, the resistance welding method, and the shape of the projection for projection welding for connecting conductors of an electric power steering apparatus. [Means for solving the problem] A resistance welding device 1000 is provided with a moving distance measuring section 1007 for measuring distances between conductors 1004 and 1005 to be joined before and after joining and evaluating joining quality based on the distances, and a projection 200 including a base 210 and a projecting surface 230 is provided to the conductor 1005 to be connected in order to easily secure a distance between the conductors after the joining.
