The present invention relates to a vehicle sound collection structure, and a sound collection device. The sound collection device (1) is provided with: a guidance unit (6) that collects sound with a microphone (3), and that guides sound emitted by an object of interest to the microphone (3); and an ejection unit (7) that promotes ejection of foreign matter entering the guidance unit (6) out of the guidance unit (6). The foreign matter that would go into the microphone (3), such as rain or dust, is ejected by the ejection unit (7) out of the guidance unit (6) even if the foreign matter reaches the guidance unit (6). Thus, the problem of accumulation of the matter, such as rain or dust, in the vicinity of the microphone (3) can be avoided, and the entry of the matter can be prevented, whereby sound collection performance can be improved.
