An in-vivo information acquiring apparatus includes an information acquiring unit that acquires in-vivo information; a power source that supplies a power to the information acquiring unit; a magnetic sensor unit that outputs a control signal corresponding to a state in which a magnetic signal externally input is detected; a pulse number counting unit that counts the number of pulses of pulse signals from the magnetic sensor unit. When the number of pulses counted by the pulse counting unit is not smaller than a predetermined number, a state in which the power from the power source is supplied to the information acquiring unit is switched to a state in which the power from the power source to the information acquiring unit is cut off.
