A functional surface of a surface acoustic wave element is disposed to face a mount surface of a circuit board on which the surface acoustic wave element is to be mounted. A gap between the functional surface and the mount surface is sealed off by an anisotropic conductive resin while an oscillation space is maintained between an oscillation transmitting area of the functional surface and the mount surface. The oscillation space is constituted by a space that is formed by the anisotropic conductive resin. A mounting structure of the surface acoustic wave element is compact, is inexpensive, and has high reliability. |
