Bump electrodes (conductive members) bonded onto lands disposed at a peripheral portion side than terminals (bonding leads) electrically coupled to pads (electrode pads) of a microcomputer chip (semiconductor chip) are sealed with sealing resin (a sealing body). Thereafter, the sealing resin is ground (removed) partially such that a part of each of the bump electrodes is exposed. The step of protruding the part of each of the bump electrodes from a front surface of the sealing resin is performed, after the grinding step.

A reinforcing element structure placed between left and right seats. A reinforcing element comprises a pair of left and right side walls positioned so as to be disposed opposite from interior faces of a pair of left and right seats, and a reinforcing member for coupling the pair of left and right side walls. The pair of left and right side walls and the reinforcing member are jointly fastened to a tunnel section. A load that acts on the reinforcing element is transferred from one of the side walls to the other side wall via the reinforcing member. The load is withstood by a highly rigid reinforcing element constituted by the left and right side walls and the reinforcing member.

A laminate support includes a layered elastic body structured by rigid plates, which have rigidity, and elastic plates, which have elasticity, being layered alternately in a predetermined layering direction, and a hollow portion is formed in the layered elastic body in the layering direction. A plastic fluid material structured by an elastic perfect plastic body (a non-hardening elastoplastic body) is placed-in the elastic body hollow portion of the layered elastic body. Further, a plurality of particle-shaped hard fillers, which are structured of a hard material which is considered to be a rigid body with respect to the plastic fluid material, are filled-in the plastic fluid material so as to be a predetermined volume fill rate. A laminate support, which can be disposed of or the like at a low cost and which can exhibit a large damping force, can be obtained.

Disclosed is a flexible metal clad laminate plate with good appearance which can be manufactured by a metalizing method such as evaporation coating, sputtering or plating. The flexible metal clad laminate plate has a polyimide film. The polyamide film is produced by reacting an aromatic diamine with an aromatic acid dianhydride to produce a polyamide acid and then imidizing the polyamide. The polyamide film has (A) an inflexion point of the storage modulus falling within the range from 270 to 340° C., (B) the peak top of tan δ; (which is a value given by dividing the loss modulus by the storage modulus) falling within the range from 320 to 410° C., (C) the storage modulus at 400° C. falling within the range from 0.5 to 1.5 GPa, and (D) the storage modulus α1 (GPa) at the inflexion point and the storage modulus α2 (GPa) at 400° C. both falling within the range satisfying Formula (1) below 85≧{(α1−α2)/α1}×100≧70.
