PROBLEM TO BE SOLVED: To attain a low cost by the reduction of the number of elements, to secure the stability of an output action even when the fluctuation exists in manufacture process and, besides, to facilitate through rate adjustment in a through-rate control type output buffer circuit. SOLUTION: A pMOS transistor 10 is driven not by an arithmetic amplifier but by an nMOS transistor 22, the nMOS transistor 11 is driven not by an arithmetic amplifier but by the pMOS transistor 23 and, besides, a bias circuit 21 is constituted of the pMOS transistors 15 and 24 and the nMOS transistor 16 and 25 without using a fixed resistance.
