Abstract
A coil unit and a manufacturing method of the same are provided which are configured to simplify the configuration of a connection portion between a coil and a wiring material (busbar), to simplify the number of components and a connection step, to prevent an increase in resistance at the connection portion, and to achieve a good connection state. A busbars-welded coil includes a coil made of a wound first metal material, and busbars made of a second metal material connected to end portions of the coil. A welded portion between the end portion of the coil and the busbar is configured by pressure welding with end surfaces butted against each other.
