Abstract
A current sensor, which senses current passing through a harness via a terminal of a battery, includes a resistor through which current passes, a current sensing circuit which measures the current passing through the resistor based on a potential difference between two positions along the direction in which current is passed through the resistor, a power supply circuit which supplies power to the current sensing circuit, and at least one capacitor which is connected to at least one of an input terminal and an output terminal of the power supply circuit to smooth input/output voltage. The resistor includes a flat energizing path, and the capacitor is disposed in an area other than a plane of projection of the energizing path on a board on which the current sensing circuit and the power supply circuit are mounted.
