Abstract
The invention provides a circuit element mounting structure including (a) a substrate having a pattern A of wirings therein, (b) at least one cavity formed at a surface the substrate, and (c) a cap for covering the cavity therewith, the cap including a pattern B of wirings therein and a recess for electrically connecting the pattern B of wirings the pattern A of wirings. The substrate includes a protrusion for electrically connecting connection B to the pattern A of wirings. The recess and protrusion are configured to engage each other. In accordance with the invention, it is now possible to mount circuit elements on a cap which had been a dead space in prior circuit, and hence also possible to mount circuit elements in higher density on a substrate including a cap zone.
