摘要：

Out of optical elements that are provided to the top end side of an inserting portion of an endoscope, a first optical element arranged closest to an observation object side and a second optical element joined hermetically to the first optical element via an air layer are joined at joined surfaces by a first adhesive. Also, peripheries of end portions of the joined surfaces are covered with a second adhesive whose moisture permeability is lower than the first adhesive.
