Abstract:
One embodiment of the light blocking blade according to the present invention is a light blocking blade for an imaging device, the light blocking blade being provided with: a magnet comprising a hole section positioned along a central axis extending in one direction; and a blade body comprising a fixing surface facing one side in the axial direction. The magnet is fixed to the fixing surface on one side in the axial direction of the blade body. The blade body comprises a through hole penetrating the blade body in the axial direction. The inner diameter of the through hole is greater than the inner diameter of the hole section. When viewed along the axial direction, the through hole surrounds the radial direction outer side of the hole section. The magnet comprises a magnet body fixed to the fixing surface via an adhesive, and a protruding section protruding from the magnet body toward the other side in the axial direction. At least a portion of the protruding section is positioned on the radial direction inner side of the through hole. The hole section opens at an end section on the other side in the axial direction of the protruding section.
