摘要:
A method of producing a multilayer wiring substrate is disclosed. The multilayer wiring substrate is free from a core substrate and includes a build up layer which includes an insulator layer and a wiring layer. One of a first main surface and a second main surface of the build up layer is formed with a metal supporting frame body. The method includes the steps of: forming a first insulator layer on a first main surface of a metal supporting plate, where the first insulator layer is included in the insulator layer and becomes a first resist layer which is positioned on the first main surface's side of the build up layer, and forming a first metal pad layer in a given position on a first main surface of the first insulator layer, where the first metal pad layer is included in the wiring layer and becomes a metal pad layer.

A method of controlling the input and output of heat to and from a heat-storing material. The method includes the step of externally supplying thermal energy to the heat-storing material capable of being supercooled and filled into a plurality of small containers together with a phase-segregation preventive agent by use of a structure for supplying heat, whereby the heat-storing material is melted. The method also includes the steps of maintaining the heat-storing material in the supercooled state after the emission of sensible heat, and releasing the supercooled state of the heat-storing material by use of a structure for releasing the supercooled state of the heat-storing material, when the release of the stored heat energy is required, whereby the heat at the melting point is generated.
