PROBLEM TO BE SOLVED: To provide an electrical horn for suppressing waterdrops or the like from entering a resonance tube and being stagnant, while increasing a sound pressure toward a vehicle front side, without expanding its original shape. SOLUTION: The present invention relates to an electrical horn 1 including: a horn housing 10; an oscillation member 11 fixed in the horn housing 10 to generate a sonic wave; and a resonance tube 25 connected to the horn housing 10 surrounding a space in contact with the oscillation member 11. In the electrical horn, the resonance tube 25 includes a sound wave inlet portion 25a and a plurality of sound wave outlet portions 25b, 25c which are turned to directions different from each other.
