Abstract:
1. A micromechanical device comprising: a substrate in which a signal line is provided on a principal surface; a micromachine which is mounted on the principal surface of the substrate, is formed of a conductive material into a beam-like shape, is elastically deformed by a function of an electric field in such a manner that the beam-like shape moves closer to or apart from the signal line, and changes electric characteristics concomitantly with the deformation; a deformation restraint section constituted of a material having a higher viscosity coefficient than the conductive material, provided on the opposite side of the micromachine to the signal line, for restraining deformation of the micromachine in a direction in which the micromachine is separated from the signal line; and a sealing body provided on the principal surface of the substrate, for covering the micromachine with a hollow section located therebetween, wherein the deformation restraint section includes a viscous section, which is formed on the micromachine, constituted of a synthetic resin material, and has surfaces covered by a cover section.
