Document Type and Number:
WIPO Patent Application WO/2019/171460
Kind Code:
A1
Abstract:
An endoscope imaging device 1 includes an imaging unit 10 that has a light receiving surface 10SA and a back surface 10SB, and a lens unit 20 that has a front surface 20SA and a rear surface 20SB. The light receiving surface 10SA of the imaging unit 10 is adhered to the rear surface 20SB of the lens unit 20, and the front surface 20SA of the lens unit 20 has a frame-like notch on the periphery. All of the external surfaces other than the front surface of the lens unit 20 and the region of the rear surface thereof to which the light receiving surface is adhered are coated with a light shielding layer 30, and all of the surfaces of the light shielding layer 30 are coated with a protective layer 40 that has a moisture vapor transmission lower than that of the light shielding layer 30.
