Next, the block-wise interleaver performs interleaving B, which is a process of inputting data in the order of the column direction as one direction, and reading the data in the order of the row direction as the other direction, NB bits by NB bits with respect to (NC−ND)×NB×NA bits representing the parity portion of an inner code indicated by P, of the product code.
