An electric current measurement method is provided with: a first controlling process of sweeping a sensing current in a negative magnetization direction in a condition that a core is saturated magnetically in a positive magnetization direction; a second controlling process of sweeping the sensing current in the positive magnetization direction in a condition that the core is saturated magnetically in the negative magnetization direction; a first specifying process of specifying a value of the sensing current if the core is demagnetized in the first controlling process; a second specifying process of specifying a value of the sensing current if the core is demagnetized in the second controlling process; and a calculating process of calculating a value of a target electric current on the basis of the specified current values, the first and second controlling processes being performed repeatedly.
