Claim:
1. A production method for a laminated coil, the production method comprising: bending a single flat coil from an initiation point, spaced apart from a first end of the flat coil, in a stacking direction to form a first coil part having the flat coil stacked in an angular tube shape of the stacking direction; forming a connection portion in the stacking direction of the first coil part by bending the flat coil of the first coil part; bending the flat coil of the connection portion in an extended state of the connection portion, in a second stacking direction to form a second coil part stacked in another annular tube shape along the second stacking direction such that the second stacking direction of the second coil part is non-parallel to the stacking direction of the first coil part; and separating the first coil part and the second coil part at the connection portion that has been bent such that the first coil part and the second coil part are disposed on the same plane.
