Provided are an endoscope and a mounting component which are capable of safely detaching a distal end cap from a distal-end-portion body.
An endoscope includes an operation part that is provided with an operation member; an insertion part that is provided on a distal end side of the operation part and is inserted into an object to be examined; an elevator that is provided in a distal end portion of the insertion part; a distal end cap that is mounted on the distal end portion and has an inner space communicating with a cap opening; an elevating operation wire of which a distal end side is connected to the elevator and which is pushed and pulled in response to operation of the operation member to operate the elevator; a wire channel through which the elevating operation wire is inserted; and a mounting component that is attachably and detachably mounted on the operation part, in which the mounting component has a wire fixing section that mechanically connects the operation member and the elevating operation wire to each other, and a jig section capable of detaching the distal end cap from the distal end portion.
