PROBLEM TO BE SOLVED: To provide a CRC code inspecting method capable of detecting a bid terminating position by one bit unit without making it necessary to separately add the bid termination information even when CRC bid parts are reversely sequenced, and suppressing the increase of a hardware circuit. SOLUTION: In this CRC code inspecting method for performing an arithmetic operation to a data polynomial by a generation polynomial, and for inspecting a signal obtained by inverting the sequence of the bids of the remainder, and adding it to the data polynomial, delay elements for the orders of the generation polynomial are disposed in the pre-stage of the input to a code generator by the generation polynomial, and information from the delay elements is reversely sequenced, and compared with the signals from the code generator.
