Abstract: There is provided a heat-conductive flexible sheet that is formed of a non-silicone material and excellent in flexibility as well as durability such as heat-aging resistance, hydrothermal resistance, and thermal shock resistance, and a heat dissipation structure using the same, as well as a resin composition that exhibits excellent handleability in the kneading step in producing a heat-conductive sheet and can be suitably used as a binder material for a heat-conductive flexible sheet.

Abstract: A conductive cushion material that can effectively shield electromagnetic wave leaking from a housing of an information device such as a cellular phone and also has a cushioning function to protect electronics parts comparatively fragile to impact, as well as a method for manufacturing the same, where manufacturing processes are simple and easy, are provided. More specifically, a conductive cushion material comprising a fiber aggregate (A) composed of conductive fine wires and an elastic resin (B) containing a conductive filler (C), characterized in that at least a part of edges of the fiber aggregate (A) is exposed out of the external surface of the cushion material, while the rest of the edges are embedded in the cushion material, and that the elastic resin (B) has many cavities therein, while uniformly mixed with the conductive filler (C), and a method for manufacturing the same are provided.
