Abstract
A coil unit and a manufacturing method of the same are provided which simplify the connection structure at the end portion of a coil to reduce the size of a stator, and minimize the work environment (equipment and work regions) when mounting the coil on the stator, and make it possible to perform efficient mounting work. A terminals-welded coil unit includes a coil made of a first metal material, and a terminal made of a second metal material connected to an end portion of the coil. A welded portion between the end portion of the coil and the terminal is configured by pressure welding with end surfaces butted against each other.
