HEAT DISSIPATION MEMBER

To provide a heat dissipation member that suppress the effects of heat and dissipate heat effectively even when a heat-generating component that is about to dissipate heat is placed in an environment that receives heat.MEANS: A heat dissipation member according to the present invention that dissipates heat from a heat-generating component includes a base material composed of a base portion that adheres to the heat-generating component and a fine concavo-convex structure portion that selectively radiates predetermined infrared rays, and a resin layer that covers the fine concavo-convex structure and transmits the predetermined infrared rays, and the resin layer contains a group of particles having a lower apparent density than the resin.SELECTED DRAWING: Figure 1 【課題】放熱しようとする発熱性部品がもらい熱を受ける環境に置かれても、もらい熱の影響を抑制して効果的に放熱する放熱部材を提供する。【手段】本発明に係る放熱部材は、発熱性部品の熱を放熱する放熱部材であって、前記発熱性部品に付着するベース部と所定の赤外線を選択的に放射する微細凹凸構造部とからなる基材と、前記微細凹凸構造を覆い前記所定の赤外線を透過する樹脂の層とを具備し、前記樹脂の層は、該樹脂よりも見掛け密度の低い粒子の群を含むことを特徴とする。【選択図】図１
