A laminated circuit board has electronic components buried therein wherein the laminated circuit board may assure excellent reliability of electrical connections and high mechanical strength even with electronic components mounted in high density. It comprises a substrate on which a land disposed on one main surface thereof is connected and fixed by solder to integrated circuit or the like, and a sheet laminated on the upper surface of the substrate and also provided with a resin fluid filling portion formed by clearance at the outer periphery of integrated circuit or the like, wherein the sheet maintains its shape by woven or non-woven cloth having a hole in which integrated circuit or the like is buried, and the woven or non-woven cloth is impregnated with resin having heat fluidity and is thermally compressed. Thus, the electrical and mechanical connections between the laminated circuit board and electronic component can be enhanced in reliability.
