To provide a vehicular sound information providing device capable of suppressing diffusion of a sound to outside a road site.SOLUTION: A loudspeaker 1 is installed for a road where vehicles pass at a place where it does not disturb passage of the vehicles, and then provides sound information for passengers of the vehicles. The loudspeaker 1 comprises: a plane loudspeaker body 11 which generates a sound from both top and reverse sides (in a vehicle ongoing direction and an opposite vehicle ongoing direction); and waveguide plates 12-14 which are extended from an upper edge, a lower edge and one side edge of the plane loudspeaker body 11 along a radiation direction of the sound of the plane loudspeaker body 11, and directs the radiation of the sound to only the passage zone of the vehicles.SELECTED DRAWING: Figure 4
