Abstract: An image pickup apparatus for endoscope includes: an optical unit having an incident surface and an emitting surface; an image pickup unit adhering to the emitting surface; an interposer where the image pickup unit is bonded to a first electrode of a first main surface; and an electric cable bonded to the interposer. The image pickup unit is smaller than the optical unit and the interposer in an outer size in a direction orthogonal to an optical axis. The image pickup apparatus for endoscope further includes a heat conductive resin with which a portion among the emitting surface, the first main surface, and a side surface of the image pickup unit is filled. The first electrode extends to a position where the first electrode is brought into contact with the heat conductive resin.

Abstract: A light-attenuation-ratio measurement method according to the present disclosure includes: a first step of placing a first light attenuator and a second light attenuator between a light source and a light-receiving portion and measuring a first intensity of transmitted light that has passed through the light attenuators, the first intensity being within a light-receiving sensitivity of the light-receiving portion; a second step of placing the second light attenuator and a target light attenuator between the light source and the light-receiving portion and measuring a second intensity of transmitted light that has passed through the light attenuators, the second intensity being within the light-receiving sensitivity of the light-receiving portion; and a third step of calculating a light attenuation ratio of the target light attenuator by multiplying or dividing an intensity ratio between the first intensity and the second intensity by a light attenuation ratio of the first light attenuator.
