Provided is a current detector which can accurately determine whether or not a transmission current is abnormal in the TDMA system. The sampling is performed on two frames in a regular manner. It is determined that the transmission current (I) is abnormal when the transmission current (I) is detected in all of the 16 slots within the two frames. If it is determined that the transmission current (I) is normal when the transmission current (I) is not detected in anyone of slots. Further, the determination result is decided when the error determination results coincide for N consecutive times. This makes it possible to accurately determine the presence/absence of an abnormality of a transmitting current in the TDMA system.
