A vehicle back door 4 includes a back door main body 12 having a window opening 18 and a back door pane 20 attached to the window opening. The back door main body has a speaker 38. The speaker is disposed below the back door pane and the angle α1 formed by a vehicle height direction axis 42 and a central axis 40 of the speaker is set to a value smaller than the inclination angle α2 of the back door pane with respect to the vehicle height direction axis. Accordingly, the sound emitted by the speaker is reflected by the back door pane and then transmitted to the front part of the vehicle interior.
