A voltage balance correction circuit includes multiple voltage correction circuits that correspond one-to-one to multiple electricity storage cells connected in series, and a control circuit that is configured to control the multiple voltage correction circuits based on voltages of the multiple electricity storage cells. The multiple voltage correction circuits include first coils that are connected to the electricity storage cells in parallel, respectively, field-effect transistors that are configured to turns on/off connections of the first coils with the electricity storage cells, respectively, under control of the control circuit, and second coils that are magnetically respectively coupled with the first coils. In the multiple voltage correction circuits, the second coils are connected in parallel.
