To overcome such a problem that various limitations are imposed on product design or component purchase since a connector and a gasket are assembled when integrating a microphone into equipment and it is necessary for an assembly marker to collect such three components and to assemble them.

The microphone is configured by bonding a connector 2 and a gasket 4 on the lower surface and upper surface of a microphone body 1. The microphone has a three-layer structure composed of planar components and in a production process, assemblies integrated by locating a large number of components in the shape of lattice, namely, an assembly of the microphone body, an assembly of a connector and an assembly of a gasket are prepared. Then, such assemblies are bonded while being piled up as they are and a laminate assembly is provided in which a large number of products is arranged longitudinally and laterally and integrated. By dicing such an assembly along the borderline of individual product areas, each divided piece forms microphones and a large quantity of products can be simultaneously provided.
