An endoscope apparatus (1) includes an insertion part (10) having an imaging mechanism at a distal end portion and which is bendable and elongated a display part which displays an image acquired by observing means a manipulating part which performs curving manipulation of the insertion part and a housing (61) which accommodates the display part and the manipulating part to a front face thereof, and which connects the insertion part with a back face opposite to the front face. The back face of the housing has a first slope (71) and a second slope (72) that rise up toward the connected insertion part, and the second slope has a first holding face (72A) and a second holding face (72B) that incline toward both ends of the housing in a right-and-left direction.
