Patent ID: 7317621

Claim:
A laminated circuit board with electronic components buried therein, comprising a substrate on which a land disposed on one main surface thereof is connected and fixed to an electrode of the electronic component by using a connecting and fixing material, a first sheet laminated on one main surface of the substrate and provided with a filling portion by fluid resin at an outer periphery of the electronic component, wherein the first sheet is provided with an opening having clearance against the outer periphery of the electronic component at a portion corresponding to the electronic component and is formed from plate-like woven or non-woven cloth impregnated with heat-fluid resin, and the first sheet and the substrate are integrated by thermo-compression bonding, and after the land is led to the other main surface at the opposite side of one main surface of the substrate by means of a first inner-via, it is again led to one main surface of the substrate by means of a second inner-via and is connected to a pattern formed on one main surface of the substrate.
