An internal state estimating device includes an electrolysis resistance calculating part calculating a post-deterioration resistance value of an electrolysis resistive component using a detection value from a sensor, a reaction resistance calculating part calculating a post-deterioration resistance value of a reaction resistive component using a resistance increase ratio and an initial resistance value of an reaction resistor, wherein the resistance increase ratio is a ratio of the post-deterioration resistance value of the electrolysis resistive component to an initial resistance value of an electrolysis resistor, and a capacitance calculating part calculating a post-deterioration capacitance value of an electric double-layer capacitive component using the resistance increase ratio and an initial capacitance value of the electric double-layer capacitive component.
