An operation input unit comprising: a substrate unit that has a switch provided thereto; and a base. An external force application part moves as a result of a button part being pressed, the external force that is made to act on the substrate unit changes in accordance with the movement of the external force application part, and, as a result, the open/closed state of the switch is changed. When the button part is not being pressed, a space is formed between the base and a substrate deflection part. When the external force application part moves as a result of the button part being pressed, the substrate deflection part is thereby deflected in the movement direction of the external force application part. |
