When carrying out puncturing of some redundant bits in an LDPC code having a check matrix of QC structure and LDGM structure, a puncture rule for preventing redundant bits which are chained to one another from being punctured is set up, and some redundant bits out of an LDPC-coded signal are punctured out of the LDPC-coded signal according to the puncture rule. As a result, redundant bits which are chained to one another can be left.
