Abstract
A surge protection device is mounted on a transmitter. A cable that sends a signal received from an external device is connected to terminal block screw portions. The connector is detachable with respect to a connector component provided in the transmitter, and outputs an input signal received from each of the terminal block screw portions to the connector component. The surge protection element absorbs a surge electric current in a case where a surge voltage is applied from the terminal block screw portions to the connector component. The terminal connector portion is connected to the terminal block screw portions via the surge protection element.
