摘要：
A microphone unit includes: a housing which has an inner space; a partition member which is provided in the housing and divides the inner space into a first space and a second space, the partition member being at least partially formed of a diaphragm; and an electrical signal output circuit which outputs an electrical signal based on vibrations of the diaphragm. In the housing, a first through-hole through which the first space communicates with an outer space of the housing and a second through-hole through which the second space communicates with the outer space are formed.
