An acoustic transducer unit includes a first member having a recess, and a plate-like second member having main surfaces. The second member is bonded to the first member so as to cover the recess and form a housing. A microphone element, which is an acoustic transducer, is accommodated in an internal space of the housing, and an acoustic path is provided between the internal space and an external space of the housing. A conductive electromagnetic-shielding member and terminal members for electrically connecting the microphone element and an external circuit are embedded in a resin body of the first member by insert molding. An electromagnetic shield layer of the second member is electrically connected to the electromagnetic-shielding member.
