To suppress variation of a distance between an end face (light emission face) of a light emitting element and an illumination lens.SOLUTION: An endoscope having an insertion part inserted into a region to be inspected is provided that includes: a chip-shaped light emitting element which is fitted to a case on a tip of the insertion part, and serves as a light source of an illumination device； an illumination lens which is provided on a tip side of the light emitting element in an irradiation direction relative to the light emitting element in the case, so as to face a light emission surface of the light emitting element, and collects light irradiated from the light emitting element and irradiates the inspected region with the light； and a position adjustment mechanism performing adjustment in such a manner that a distance between the light emission surface of the light emitting element and a facing surface of the illumination lens facing the light emission surface of the light emitting element becomes a prescribed value.SELECTED DRAWING: Figure 4【課題】発光素子の端面（発光面）と照明用レンズとの間の距離のばらつきを抑制する。【解決手段】被検部位に挿入される挿入部を有する内視鏡であって、前記挿入部の先端のケースに取り付けられ照明装置の光源となるチップ状の発光素子と、前記ケース内において前記発光素子よりも前記発光素子の照射方向の先端側に、前記発光素子の発光面に対向するように設けられた、前記発光素子から照射された光を集光して前記被検部位に照射する照明レンズと、前記発光素子の前記発光面と前記照明レンズの前記発光素子の発光面に対向する対向面との距離が所定の値になるように調整する位置調整機構と、を有する内視鏡。【選択図】図４
