The integral current detector is capable of detecting an integral current amount of the normal bias voltage at the time of applying the normal bias voltage and an integral current amount of the reverse bias voltage at the time of applying the reverse bias voltage. The controller controls the bias voltage application device so that an absolute value of the integral current amount of the reverse bias voltage is in the range of not less than 0.2% and less than 25% of an absolute value of the integral current amount of the normal bias voltage.

The second unit receives frames over the channel. The third unit determines an error characteristic in the received frames and/or a busy status of the channel. The controller controls at least either one of whether to change the frequency channel or not, and whether to change a duration of an interframe space or not.
