A switch-operation-determining device provided with a determination circuit for determining whether a switch has been operated, wherein the determination circuit is provided with: a first resistor, a first diode, and a second diode serially connected in the stated order from the power-source side, such that current flows from the power source toward a ground; and a control unit for comparing the anode potential of the first diode and a threshold potential, and determining that the switch has been operated when the anode potential of the first diode is lower. Of the first diode and the second diode, it is the second diode that is connected in parallel with the switch.
