PROBLEM TO BE SOLVED: To realize a serial-parallel converter circuit capable of setting a data width so as to avoid power concentration.SOLUTION: A serial-parallel converter circuit includes: a plurality of conversion stages 51 to 54 (where K and N are positive integers satisfying KN) each converting input K-bit data to N-bit data and connected such that output data from a front conversion stage serves as the input data to a rear conversion stage; and an output circuit including physically continuous 2output selection circuits the number of which corresponds to a predetermined number of bits M that are the number of bits of the output data from the last conversion stage of the conversion stages, and selecting either the output data from the last conversion stage of the conversion stages or the output data from the conversion stage before the last stage to output the selected output data, the output data from the conversion stage before the last conversion stage being input to the physically discontinuous output selection circuits of the output circuit.
