A tip of an endoscopic insertion section includes a tip body having a forceps hole, and a cap covering the distal face of the tip body and having an opening corresponding to the forceps hole. Protrusions are provided between the distal face of the tip body and the opposite face of the cap that is opposite to the distal face, so that a specified space is formed between the distal face and the opposite face with the protrusions. In the space, at least a region around the forceps hole is filled with an adhesive so as to adhere the tip body and the tip cap together with no voids in the adhesive surrounding the forceps hole and thereby prevent disadvantages due to the entrance of a body fluid or a chemical cleaning solution through such voids.
