PROBLEM TO BE SOLVED: To provide an insertion part shielding structure of an endoscope with which a sheet is hardly torn even when the sheet and a connection rivet rub against each other by repeated bending motion and a stable insulation performance can be maintained for a long time without changing the diameter of a hard part of the tip. SOLUTION: The periphery of a shielding case in the hard part of the tip is covered with an electrical insulation film and a part of the electrical insulation film is in contact with the connection rivet. The electrical insulation film is made of a combination of a non-adhesion sheet without an adhesive layer and an adhesion tape with the adhesive layer, and the non-adhesion sheet is in contact with the connection rivet.
