First claim
Opening claim text (preview).
What is claimed is: 1. A coil unit to be attached to an externally provided attachment target member, the coil unit comprising: a case made of a resin, the case including an attachment surface to be attached to the attachment target member; a metal plate provided in the case; a coil located opposite to the attachment surface with respect to the metal plate, the coil being embedded within a wall of the case; and a metal member arranged between the metal plate and the attachment surface and formed integrally with the case, the metal member being arranged to surround a space located between the metal plate and the case, wherein the case is attached to the attachment target member with a fastening member, wherein the attachment surface of the case is provided with an insert portion where the metal member is provided and a fastening portion pressed against the attachment target member by fastening force from the fastening member while the case is attached to the attachment target member, and wherein the insert portion of the attachment surface protrudes outward relative to the fastening portion of the attachment surface while the case is not attached to the attachment target member. 2. The coil unit according to claim 1 , wherein the attachment target member is made of a metal, and the metal member is exposed through the case in the insert portion of the attachment surface. 3. A coil unit to be attached to an externally provided attachment target member, the coil unit comprising: a case made of a resin, the case including an attachment surface attached to the attachment target member with a fastening member; a metal plate provided in the case; a coil located opposite to the attachment surface with respect to the metal plate; and a metal member arranged between the metal plate and the attachment surface and formed integrally with the case, wherein the metal member being arranged to surround a space located between the metal plate and the case, the attachment surface of the case is provided with an insert portion where the metal member is provided and a fastening portion, and the insert portion of the attachment surface protrudes outward relative to the fastening portion of the attachment surface while the case is not attached to the attachment target member.
