A Walsh code generator capable of performing signal processing at a high speed using the codewords of the Walsh code. A binary counter 3 generates a count signal counting upper (n-m) digits of a codeword number corresponding to a codeword of a Walsh code of plural bits. A parallel generation controller 4 generates, by the count signal and upper (n-m) bits of the codeword number, a parallel generation control signal for causing bits making up the codeword to be generated in parallel. A parallel Walsh code generator 5 generates the codeword in parallel by the parallel generation control signal and the lower m bits of the codeword number. The Walsh code generator may be reduced in the maximum operating frequency, while its power consumption may be lowered.
