PROBLEM TO BE SOLVED: To provide an output buffer circuit in which the voltage of an output signal is prevented from oscillating, and a high data read-out rate can be ensured for a recorder when it is provided with the output buffer circuit. SOLUTION: The output buffer circuit 6 comprises a PMOS 2 having a source connected with a power supply terminal VDD and a gate connected with an input terminal 4a, a resistor 11 having one end connected with the drain of the PMOS 2 and the other end connected with the output terminal 5, a resistor 12 having one end connected with the output terminal 5, and an NMOS 3 having a drain connected with the other end of the resistor 12, a gate connected with the input terminal 4b and a source connected with the reference power supply terminal VSS wherein the resistance of the resistor 11 is 2-4 times as high as the equivalent resistance of the PMOS 2 and the resistance of the resistor 12 is 2-4 times as high as the equivalent resistance of the NMOS 3.
