A method for manufacturing an ion sensor is provided in which an ion-sensitive film is adhered to an electrode body that accommodates an internal solution and has an internal electrode. The method includes an application step for applying water to a placement surface of the electrode body on which the ion-sensitive film is to be placed; a placement step for placing the ion-sensitive film in a state in which water is present on the placement surface; a pressurizing step for pressurizing the ion-sensitive film from the opposite side of the electrode body; and an irradiation step for irradiating a laser beam from the opposite side of the electrode body in a state in which the ion-sensitive film is pressed against the electrode body.
