Claim Text:
1. An electrical component resin comprising: a plurality of particles of a phase-change-material that phase-changes by heat absorption; the plurality of phase-change-material particles being individually encapsulated with a first electrical insulating material that encloses the phase-change-material to form capsules, with a diameter between 2 micrometers and 100 micrometers; a layer provided between each capsule and the encapsulated phase-change-material and partially enclosing the phase-change-material; and a resin formed of a second electrical insulating material and enclosing the capsules; wherein the layer is composed of inert gas different from the phase-change-material; a substrate comprising an electric circuit composed of layers of the electrical component resin, the electrical component resin containing one of an electrical component and a conductor pattern, the layers being stacked sequentially or with an intermediate layer interposed between the layers.
