Abstract

A current breaker includes a semiconductor substrate in which a switching element is provided, a first electrode provided on a surface of the semiconductor substrate, a second electrode provided on the surface and separated from the first electrode, a resistive film provided on the surface and connecting the first electrode and the second electrode, a terminal, a bonding wire connecting the first electrode and the terminal, and a control element configured to turn on the switching element when a voltage between both ends of a current path including the resistive film exceeds a threshold value. The switching element is connected to at least one of the first electrode and the second electrode.
