Abstract: PROBLEM TO BE SOLVED: To prevent the disconnection of a bump connection part due to thermal stress difference by laminating chip mounting boards interposing laminated sheets each of which is composed by forming through holes arranged at equal intervals in an elastic insulator, and filling the through holes with a soft metal. SOLUTION: Boards 1 are laminated into a sandwich-like four-layer form by interposing an interlayer sheet 3 between each pair of layers of the upper board 1 on which a chip 2 is mounted and the lower board 1 on which another chip 2 is mounted. The laminated four-multichip structural body is overlaid on a mother board 8. Only a chip mounting part of each of the interlayer sheets 3 is hollowed so as not to cover the chip mounting part of the corresponding board. The interlayer sheet 3 comprises an elastic insulator 4 and a soft metal 5, and the soft metal 5 is formed into a grid-like or honeycomb shape at equal intervals. The dimension between grids is less than half as much as the distance between electrode pads 6 of chip mounting boards.  The interlayer sheet 3 is composed of the soft metal 5 and the elastic insulator 4, being easy to deform and absorbs and relaxes the stress due to the difference between the thermal expansion coefficient of the upper board 1 and that of the lower board 1.
