Abstract: Provided is a current measuring device for measuring current, including a conductor adapted to pass current therethrough, at least a pair of voltage sensing terminals arranged apart from each other on the conductor in the current flowing direction, and a substrate to which the voltage sensing terminals are connected. The substrate is long in the current flowing direction, and connection portion of the substrate that are connected to the voltage sensing terminals are arranged closer to one end side of the substrate in the lengthwise direction.
