The invention discloses an inspection apparatus of an electrical storage device. The inspection apparatus includes a power supply device; positive and negative conductive lines, connected to the powersupply device and having corresponding first and second probes, at corresponding front ends; a resistor and a switch serially disposed between the positive conductive line and the negative conductiveline; a circuit resistance calculation unit that calculates a circuit resistance value based on a difference in voltage between when the switch is turned off and turned on; an inspection unit configured to inspect the electrical storage device; and a virtual resistance setting unit that increases the output voltage after the start of inspection.
