A current detection apparatus for detecting a current from a battery flowing through a harness. The apparatus includes a resistor having first and second fixed portions secured and electrically connected to a battery-side wiring and the harness, respectively, a circuit board provided with a current detection circuit for detecting a current flowing through the resistor on the basis of a potential difference between two positions along a current carrying path between the first and second fixed portions of the resistor, and a casing for housing the resistor and the circuit board. The resistor includes a current carrying member that provides the current carrying path and a lead member electrically connecting the current carrying member and the circuit board. The first and second fixed portions, and the current carrying member are disposed on the top surface of the battery, and the circuit board is disposed on a side of the battery.
