To provide a coil unit that can secure strength and reduce the board thickness of a case body and a cover member.SOLUTION: A coil unit includes a case body 4 including a housing space that houses a coil formed spirally and a wiring board to which the coil is connected, and a first cover member 5 that covers the housing space. The case body includes a center boss part 47 (first support member) with a cylindrical shape that projects to a side of the first cover member. The first cover member includes a second support member 57 with a cylindrical shape that projects to a side of the case body. In a state where the first cover member is attached to the case body, the first support member and the second support member are disposed in a nest structure and the first support member is in contact with the first cover member to support the first cover member, and the second support member is in contact with the case body to support the case body.SELECTED DRAWING: Figure 21

    【課題】強度を確保すると共に、ケース本体とカバー部材の板厚を薄くすることができるコイルユニットを提供する。【解決手段】コイルユニットは、渦巻き状に形成されたコイルと、コイルが接続される配線基板と、を収容する収容空間を有するケース本体4と、収容空間を塞ぐ第1カバー部材5と、を備える。ケース本体は、第1カバー部材側に突出した筒状の中央ボス部47(第1支持部材)を有する。第1カバー部材は、ケース本体側に突出した筒状の第2支持部57を有し、第1カバー部材がケース本体に取り付けられた状態において、第1支持部及び第2支持部が入れ子状に配置され、第1支持部が第1カバー部材に当接して第1カバー部材を支持するとともに、第2支持部がケース本体に当接してケース本体を支持する。【選択図】図21
