ABSTRACT:
An assembled body of an electronic endoscope which is capable of reducing the diameter of the endoscope and simplifying the structure thereof. The assembled body comprises an imaging device with a color filter and a microlens provided on the imaging plane, and an objective optical member for catching an object of inspection. An opening is formed in a cover glass as the objective optical member, and the cover glass is directly adhered to the imaging plane of the imaging device. An air gap is set by the opening of the cover glass. The cover glass and the imaging device are adhered to each other with an adhesive so as to keep the air gap in an airtight state. It is thus possible to directly combine the imaging device with the optical member without using a package. A groove may be formed as the air gap in a prism as a part of the objective optical member.
