Abstract
Provided is a closing plug capable of easily closing an open end of a flow passage without concern of scale. The closing plug includes: a gasket configured to come into contact with an annular projection formed in a step portion inside the open end of the flow passage of a flow passage block; a columnar pressing member formed by cutting out an inner side of a pressing surface so as to press a peripheral edge portion of the gasket; and a closing plug screw configured to be screwed into a female screw formed in an inner peripheral surface on an open end side from the step portion and press the pressing member toward the gasket by movement caused by screwing.
