The present utility model relates to a fuse, a vehicle circuit for an electric vehicle, and an electric vehicle. The fuse has a longitudinal direction and a transverse direction, and includes: a bushing, having a through-hole cavity extending in the longitudinal direction and for accommodating quartz sand; a fuse body, accommodated in the through-hole cavity and having a plurality of openings spaced apart from each other in the transverse direction; and two contact blades, positioned at two ends of the through-hole cavity and each soldered to the fuse body by a conductive plate. An arc extinguishing medium layer is provided on the fuse body. A side edge of the arc extinguishing medium layer contacts edges of any two adjacent openings of the plurality of openings so as to cause the arc extinguishing medium layer to be close to a minimum transverse spacing between the two opening edges.
