An insulating substrate is prepared. In this substrate, plural via holes penetrating in a thickness direction are filled with a conductive paste. This paste is produced by adding an organic solvent to a powder of an, and by processing the power of the alloy to a paste. The substrate is then pressed from a front surface and a back surface of the substrate, while being heated. The conductive paste is solid-phase sintered and interlayer connecting members are formed. A front surface protective member is disposed on a front surface of the substrate and a back surface protective member is disposed on a back surface of the substrate, and a laminate is formed. The laminate is integrated by a lower pressure being applied while heating at a lower temperature, compared to the temperature and pressure in the process of forming the interlayer connecting members.

A strain detector is interposed between a base and an attachment member in a structure body having the base, the attachment member, and the stainless bolts fixed the base to the attachment member. The strain detector includes an elastic member and a heat flux sensor. The elastic member is provided to compress or extend in accordance with a deformation of the stainless bolts, and the elastic member generates heat based on the compression and absorbs heat based on the extension. The heat flux sensor is deformed in accordance with the compression or the extension of the elastic member and the heat in the elastic member is transferred to the heat flux sensor. The heat flux sensor can detect a magnitude of the heat flux Fh1 as a heat stream between the inside of the elastic member and the outside, generated by the compression or the extension of the elastic member.
Abstract:
In a step of pressing a laminate, the laminate is first pressed while being heated to a temperature lower than a melting point of a thermoplastic resin so as to elastically deform the thermoplastic resin and apply a pressure in a direction perpendicular to a laminating direction to thereby allow first and second conductive pastes to tightly adhere to front and rear surface patterns. Next, the laminate is pressed while being heated to a temperature equal to or higher than the melting point of the thermoplastic resin so as to fluidize the thermoplastic resin while allowing the thermoplastic resin to flow out from the laminate and apply a pressure in the direction perpendicular to the laminating direction to thereby allow the first and second conductive pastes are solid-sintered.
