PROBLEM TO BE SOLVED: To obtain an error correction apparatus having high error correction capability by generating a highly accurate erasure flag. SOLUTION: The error correction apparatus is provided with an error correction means 4 for applying an error correction processing to one of a plurality of input signals to output a first error position signal corresponding to a position of error data in the one input signal and a first signal corresponding to the result of the error correction processing, and an error position signal generating means 5 for outputting a second error position signal corresponding to a position of error data in the other input signals based upon the first error position signal outputted from the error correcting means 4, and on the basis of the second error position signal, the error correction means 4 applies the error correction processing to the other input signals to output the second signal.
