An electrical horn includes a horn housing, an oscillation member located at the horn housing to generate a sonic wave, and a resonance tube in which the sonic wave generated by the oscillation member flows. In the electrical horn, the resonance tube has a plurality of sonic outlet portions that are open in different directions. Accordingly, when the electrical horn is mounted to a vehicle, it is possible to reduce an amount of foreign material entering into the resonance tube while increasing a sonic pressure toward a vehicle front side.
