The sound capturing structure is provided with a main body having a through hole, one end of the through hole serves as a sound introducing portion, and the other end thereof serves as a sound receiving portion. For a sound introduced from a part, a noise attenuation part having a cross-sectional area such that the attenuation amount is a region including a sound of a reference frequency or less a region exceeding the reference frequency is formed, and the reference is provided at the one end of the main body.
