PROBLEM TO BE SOLVED: To improve the winding reliability of a wound coil. SOLUTION: The core member 12 of a wound coil 10 is equipped with a sloping face 20 extending from the wound part 24 of a winding 14 to a winding leading part 14a connected to an electrode 22. By this setup, a gap between the leading part 14a extending from the wound part 24 to the electrode 22 and a flange 18 becomes small, and a coating agent is restrained from penetrating into the gap and staying there, so that the winding is restrained from being extended and disconnected due to expansion/contraction of the coating agent.
