An endoscopic system according to the present invention includes an endoscope (2) which has channel openings (23 to 26) (channel tip ends 40a, 43a, and 45a) and a ventilating unit (37) which is a steam entrance, and a container (34) which has a tray (35) housing the endoscope (2) in a predetermined state. A restricting portion (49) is formed on the tray (35) so as to restrictively house the endoscope (2) in depressions. The restricting portion (49) includes a first to a fourth restricting areas (49a to 49d) corresponding to the channel openings (23 to 26) (40a, 43a, and 45a) and the opening of the ventilating unit (37). The first to the fourth restricting areas (49a to 49d) are formed so as to have clearances (gap portions) (49A to 49D) and a cross-sectional area of each of the clearances is wider than a cross-sectional area of the corresponding opening.
