An endoscope having an insertion portion to be inserted into an object to be observed, includes: a substantially tubular holder member mounted to the insertion portion and having an open front end portion including a shoulder surface surrounded by an axial wall; a lens barrel holding an objective lens system and received in the holder member; and a light-transmissive closure member fitted into a front opening defined by the axial wall, and fixed to the front opening by a bonding agent interposed between an outer circumferential surface of the closure member and an opposing inner circumferential surface of the open front end portion of the holder member, wherein a space axially adjoining the shoulder surface is defined between an outer circumferential surface of a front end portion of the lens barrel and an opposing inner circumferential surface of the holder member.
