A decoding apparatus includes a first decoder and a second decoder performing iterative decoding on each of a plurality of code blocks, each as a decoding unit, contained in a transport block, and a stop/end determination section determining whether or not to stop iterative decoding based on an output result from the second decoder. The stop/end determination section determines whether or not to stop the iterative decoding on each code block based on a determination result on whether error correction of iterative decoding in each code block is converted or not, and further determines whether or not to stop the iterative decoding of the transfer block based on the determination result in each code block. If it is determined that error correction of iterative decoding is not converted in one code block, the decoding process of the transport block containing the relevant code block is stopped.
