Abstract
An overcurrent cutoff device includes a heat generating unit located in series with a path leading from a battery B for a vehicle to a motor via a wire, and a heat sensing unit with characteristics varying with the temperature supplied from the heat generating unit. The overcurrent cutoff device cuts off overcurrent by activating a switching element, based on a signal in accordance with the temperature obtained from the heat sensing unit. The overcurrent cutoff device includes an overcurrent detecting element in which the heat generating unit and the heat sensing unit are integrally covered with a molded resin section.
