A microphone unit U1 includes a substrate 100, a microphone 200, a fixing member 300, and a film 400. The substrate 100 includes a first face 101, a second face 102 opposite to the first face 101, and a through-hole 103 extending from the first face 101 to the second face 102 through the substrate 100. The microphone 200 includes a sound hole 260 and is mounted on the second face 102 of the substrate 100 such that the sound hole 260 communicates with the through-hole 103 of the substrate 100. The fixing member 300 is fixed on the first face 101 of the substrate 100 such as to be located around the through-hole 103. The film 400 provides at least one of dustproofness and waterproofness.
