Abstract: An endoscope button for an endoscope including a cylinder communicating with tubes includes: a first unit and a second unit that are attachable and detachable with respect to a fitting part fixed to the cylinder, and that are separable from each other in a state being removed from the fitting part. The first unit has a cylindrical shape, and includes a cylindrical member that is attachable and detachable with respect to the fitting part. The second unit includes: a fixing member that is inserted inside the cylindrical member in a state in which the endoscope button is attached to the fitting part, and is fixed to the cylindrical member; and a first movable member that is installed movably with respect to the fixing member, and that is movable back and forth inside the cylinder in the state in which the endoscope button is attached to the fitting part.
