Abstract: An objective optical system for endoscope includes a first group having a negative refractive power, an aperture stop, and a second group having a positive refractive power. The first group includes a negative meniscus lens having a convex surface directed toward the object side, and a positive lens having a convex surface directed toward the object side. The second group includes a predetermined lens, a positive cemented lens, and a positive single lens, or includes the predetermined lens, the positive single lens, and a positive cemented lens. The predetermined lens is a meniscus lens having a convex surface directed toward an image side. and an image-side lens, and the following conditional expressions (1′), (2), and (4′) are satisfied: 0.7

Abstract: An imaging unit includes: a columnar optical member including an incident surface on which light is incident, a reflecting surface for reflecting the light incident from the incident surface in a direction different from the incident surface, and an emission surface for causing the light incident from a direction orthogonal to the incident surface and reflected from the reflecting surface to travel in a straight line and emitting the light to the outside; an imaging device including a light receiving unit, formed on a surface of the imaging device, for receiving the light emitted from the emission surface and performing photoelectric conversion on the light; and a cylindrical imaging holder, protruding from at least part of an outer edge of one end in line with a side surface shape of the optical member, for defining the position of the incident surface and holding the optical member.

Abstract: This endoscope imaging device is to improve focus adjustment accuracy between an imaging element and an objective lens. This endoscope imaging device has an objective lens unit frame holding objective lenses, and an imaging element supporting frame fitted onto an outer side of the objective lens unit and holding an imaging element. The lateral cross-sectional shape of a fitted portion of an outer surface of the objective lens unit frame and the lateral cross-sectional shape of a fitted portion of an inner surface of the imaging element supporting frame are different, and in the fitted portions, a contact portion where said two frames come into contact, and a gap portion where said two frames do not come into contact are formed, and also the objective lens unit frame and the imaging element supporting frame are cemented by a photosetting glue filled in the gap portion.
