HEAT-DISSIPATING MEMBER AND MANUFACTURING METHOD THEREOF
To improve the manufacturing stability (such as the yield) in manufacturing, e.g., a power module by connecting a component to one surface of a curved heat-dissipating member.SOLUTION: There is provided a plate-shaped heat-dissipating member provided with a metal-silicon carbide composite comprising aluminium or magnesium, in which at least one of two main surfaces of the heat-dissipating member is curved in a convex shape toward the exterior of the heat-dissipating member. If frefers to the flatness of one of the main surfaces as stipulated by JIS B 0621, and frefers to the flatness of the other of the main surfaces, which is not the one of the main surfaces, as stipulated by JIS B 0621, then fis at least 10 μm smaller than f.SELECTED DRAWING: Figure 1
【課題】湾曲した放熱部材の片面に部品を接続してパワーモジュール等を製造に当たって、その製造安定性（歩留まりなど）を改善すること。【解決手段】アルミニウムまたはマグネシウムを含む金属−炭化珪素質複合体を備えた板状の放熱部材であって、放熱部材の２つの主面のうち少なくとも一方の主面は、放熱部材の外側方向に凸型に湾曲しており、その一方の主面の、ＪＩＳ Ｂ ０６２１で規定される平面度をｆ１とし、その一方の主面とは異なる主面である他方の主面の、ＪＩＳ Ｂ ０６２１で規定される平面度をｆ２としたとき、ｆ２のほうがｆ１よりも１０μｍ以上小さい放熱部材。【選択図】図１
