An object of the present invention is to provide a direct-connect fuse unit for a battery terminal that can restrain from being upsized and can mount various kinds of electrical components. A conducting hardware is integrally provided with a connecting terminal. The connecting terminal is bent in a plate thickness direction of the conductive hardware to project from a surface of a casing. An electrical component housing contains and holds an external electrical component connected to the connecting terminal. The electrical component housing is separated from the casing and is adapted to be fitted in the casing.
