Abstract:
One embodiment of this light-shielding blade is a light-shielding blade for an imaging device, wherein the light-shielding blade comprises a blade body having a fixing surface, and a magnet fixed to the fixing surface with an adhesive. One member, among the blade body and the magnet, has a hole part disposed along a center axis extending in one direction and passing through the one member in the axial direction, and the other member among the blade body and the magnet is disposed on one side in the axial direction. The other member has a through hole passing through the other member in the axial direction. The inner diameter of the through hole is greater than the inner diameter of the hole part, and viewed along the axial direction, the through hole surrounds the outer side in the radial direction of the hole part. The adhesive has: a first adhesive part that adheres the circumferential edge of the through hole at the end on one side in the axial direction of the other member to the end part on the other side in the axial direction of the one member; and a second adhesive part that is exposed on the inner side in the radial direction of the through hole, and adheres the inner-side surface in the radial direction of the through hole to the end part on the other side in the axial direction of the one member.
