In a multiplex communication method for implementing multiplex communication between a plurality of circuit units, a format of a transmitted data signal not only is formed of serial data consisting of first data, second data that has the same content as the first data, and a parity that indicates the number of logical 1s or logical 0s forming the first data and the second data is even or odd, but also selects as regular data in such a manner that when the transmitted data signal is received, if the first data and the second data are compared with each other and judged to be coincident with each other from the comparison, then the coincident data is selected as the regular data and that if the first data and the second data are judged to be different from each other from the comparison, then a logic of the parity is checked and either the first data or the second data corresponding to the logic of the parity is selected as the regular data.
