A hood for endoscope is attached to an endoscope that includes an insertion portion, a distal end portion, and a conduit, the hood for endoscope including a frame mounted to an outer circumference of a distal end portion, a discharge opening that communicatively connects an inner circumferential surface and an outer circumferential surface of the frame and is provided to be slanted to be oriented in a longitudinal axis direction, and a straightening plate with which a gas ejected from the discharge opening towards a front side in the longitudinal axis direction collides and which guides the gas from a flowing orientation of the gas in the longitudinal axis direction to the flowing orientation of the gas in a radial direction in such a manner that the gas is caused to pass through the discharge opening from an inside of the frame and flow towards an outside of the frame.
