PROBLEM TO BE SOLVED: To easily bring a coil end 4 of winding start side into close contact with a winding start portion holding face 22 of a bobbin 1 for coil winding. SOLUTION: In the bobbin 1, the winding start portion holding face 22 formed on the other end surface of an end holder 7 has a distance to a reference flat plane, which increases as a position on the face 22 advances radially. As a result, the coil end 4 pulled out to one of axial directions is more easily brought into close contact with the winding start portion holding face 22, compared with a prior art case where the surface is formed perpendicularly to the axial direction.
