PROBLEM TO BE SOLVED: To constitute a vehicle horn so that a sound pressure is be lowered and waterproofness is excellent. SOLUTION: The vehicle horn is constituted by unifying an oscillation generating unit H and a resonance unit R. When the vehicle horn is attached to a vehicle in such an attitude that the resonance unit R is positioned under the oscillation unit H, and a sound outputting section 13e formed in the resonance unit R faces forward, a bottom face 13h of a sound path 13d is formed in an inclined plane which is gradually lowered from a sound input section 13c side to the sound output section 13e side.
