Abstract: A management device for an energy storage device, the energy storage device being mounted in a vehicle and configured to supply power to a specific load that consumes power during parking. The management device includes: a circuit board equipped with a processing unit; a resistor that detects a current of the energy storage device; and a connecting member that electrically connects the resistor and the circuit board. The processing unit calculates SOC of the energy storage device based on the current detected by the resistor. The connecting member includes a signal line, and a shield layer that shields the signal line. One end of the signal line, is connected to the resistor by welding and joining, and the other end of the signal line, is connected to the circuit board by welding and joining.
