Summary:PROBLEM TO BE SOLVED: To reduce the article-numbers of lead frames to be prepared, by unifying the shape until a pre-stage for mounting a coil finally, regardless of the arrangement posture of the coil (vertical, horizontal).SOLUTION: In a lead frame 10 for coil mounting, a coil mounting plate 18 for mounting a coil 50 is provided at a part of a planar lead frame body 1A including terminals 12, 15P, 16P on the periphery. Depending on the presence or absence of a bend at a coupling portion for the lead frame body 1A, the coil mounting plate 18 can select a first coil mounting posture for vertical arrangement located on a plane perpendicular to the lead frame body 1A, or a second coil mounting posture for horizontal arrangement located on a plane in parallel with the lead frame body 1A.SELECTED DRAWING: Figure 1 【課題】コイルの配置姿勢（縦置き・横置き）によらず、最終的にコイルを実装する前段階までの形状を統一することで、用意するリードフレームの品番を少なくする。【解決手段】コイル実装用のリードフレーム１０において、周辺部に端子部１２，１５Ｐ，１６Ｐを備えた平面状のリードフレーム本体１Ａの一部に、コイル５０を実装するためのコイル実装板部１８が設けられ、コイル実装板部１８がリードフレーム本体１Ａに対する連結箇所の折り曲げの有無により、リードフレーム本体１Ａに垂直な平面上に位置する縦置き用の第１のコイル実装姿勢と、リードフレーム本体１Ａと平行な平面上に位置する横置き用の第２のコイル実装姿勢と、に選択可能とされている。【選択図】図１
