A signal conversion circuit (2) according to an embodiment of the present invention includes a differential amplification unit (10) and a source follower unit (20). The differential amplification unit (10) has a first and a second resistor (11, 12) connected in series, a third and a fourth resistor (13, 14) connected in series, a first and a second PMOS transistor (15, 16), and a current source (18). The source follower unit (20) has a first and a second NMOS transistor (22, 24). The source of the first NMOS transistor (22) is connected between the first and the second resistor (11, 12). The source of the second NMOS transistor (24) is connected between the third and the fourth resistor (13, 14).
