CURRENT DETECTING DEVICE
First Claim
1. A current detecting device that detects a current flowing through a battery terminal to a harness comprising:
- a fixed part to which the harness is fixed and electrically connected;
a resistor inserted between the battery terminal and the fixed part;
a circuit board in which a current detection circuit is mounted, the current detection circuit detecting current flowing through the resistor based on a potential difference between two points along an energizing direction of the resistor; and
a case housing the resistor and the circuit board, wherein,the fixed part to which the harness is fixed and electrically connected is disposed within a battery upper surface area.

Abstract
A current detecting device includes a second fixed part to which the harness is fixed and electrically connected, a bus bar as a resistor inserted between a first fixed part and the second fixed part, a circuit board in which a current detection circuit is mounted, the current detection circuit detecting current flowing through the bus bar based on a potential difference between two points along an energizing direction of the bus bar, and a case accommodating the bus bar and the circuit board. The second fixed part to which the harness is fixed and electrically connected is disposed within a battery upper surface area.
