PROBLEM TO BE SOLVED: To prevent breakage of a leg, while ensuring the connector holding strength, in a holding member including a leg being inserted into a through hole and reflow soldered.SOLUTION: A holding member (26) includes a base (40) fixed to a connector (20), and a leg (42) extending from the base toward a through hole (30). One leg is inserted into one through hole, and a first leg (44) is reflow soldered as the leg, and projects to the back side (16b). The first leg has an insertion part (46) inserted into the through hole, and a linking part (48) for linking the insertion part and the base. In the insertion part, a cross-sectional area at the same position as one side is S1b, a cross-sectional area at the same position as the back side is S1s, and a minimum cross-sectional area of the linking part is S2s. The first leg is formed to satisfy the relations; S1b>S1s and S2s>S1s. |
