PROBLEM TO BE SOLVED: To provide an LDPC code decoder capable of increasing a processing throughput without degrading quality. SOLUTION: The LDPC code decoder, which applies an algorithm for updating a decoding result for every row processing as a decoding algorithm in LDPC codes, has: a decoding processing means for carrying out decoding processing; a processing wait information holding means for holding time information, determined from information of a check matrix for the LDPC code to be decoded, to enable a target row to start processing after start of decoding processing for a row preceding to the target row; and a start instruction suspending means instructing the decoding processing means to start decoding processing to the target row after waiting for at least the time information held by the processing wait information holding means.
