An error-correcting code processing method includes: calculating descending symbols or ascending symbols or both, and calculating, as a parity, exclusive OR of all elements of an information symbol sequence; one or both of calculating exclusive OR for each element of the descending symbols, to generate low-order n bits of the descending symbols and calculating exclusive OR for each element of the ascending symbols, to generate low-order n bits of the ascending symbols; one or both of calculating exclusive OR of elements obtained by selecting, in descending order, elements from an element sequence resulting from arranging parities, to generate a high-order m bit of the descending symbols and calculating exclusive OR of elements obtained by selecting, in ascending order, elements from the element sequence, to generate a high-order m bit of the ascending symbols; and outputting the descending symbols or the ascending symbols or both as check symbols or a syndrome.
