A Hall element outputs a Hall voltage generated at a first terminal pair or a second terminal pair to first and second output terminals by switching the voltage in a first status and a second status. Based on the voltages of the first and the second output terminals and a reference voltage, first and second capacitors are charged. Then, the voltages of the first and the second capacitors are compared, and a detection signal is obtained. Thus, a magnetic sensor circuit which reduces influence of an element offset voltage of the Hall element and also reduces influence of an input offset voltage generated at an amplifier, and a portable terminal provided with such magnetic sensor circuit are provided.
