<p><P>PROBLEM TO BE SOLVED: To reduce size, by improving the mounting efficiency by building into a multilayer structure and to increase the reliability by having a functional element body operate stably. <P>SOLUTION: The functional element body 5 is sealed in the layer of the multilayered structure of a module board 2 and a wiring board 4 which are stacked via a prepreg 3, in such a manner that a functional surface 5a formed with a movable portion 5b may face a concave portion 6. The functional element body 5 is built in and shielded, between the first shield pattern 12 of the module board 2 and the second shield pattern 18 of the wiring board 4, which are interlayer-connected by a grounding via 19 extending through the prepreg 3. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
