    • A portable information processing apparatus is configured to dissipate heat generated in a cabinet mainly from a part which a user hardly touches, and thus the temperature at a palm rest is suppressed. The cabinet includes a heat conducting spacer 16 provided over a heat-generating component 15 to conduct heat thereof, a heat absorption area 10ah to absorb the heat of the heat-generating component 15 through the heat conducting spacer 16, and a heat conduction obstructing area 10rb provided on a heat conduction path between the heat absorption area 10ah and the palm rest 11 to reduce a cross-sectional area of the heat conduction path. Accordingly, heat conduction from the high-temperature heat generating component 15 to the palm rest 11 is restricted, and thus the temperature of the palm rest 11 can be limited.
    • 便携式信息处理装置被配置为主要从用户几乎不触摸的部分散发在机柜中产生的热量,从而抑制掌托处的温度。 机柜包括设置在发热部件15上方以传导热量的导热间隔件16,吸热区域10ah,以吸收发热部件15通过导热间隔件16的热量,以及热传导阻挡区域 10rb设置在吸热区域10ah和掌垫11之间的热传导路径上,以减小热传导路径的横截面面积。 因此,从高温发热部件15到掌垫11的热传导受到限制,能够限制掌垫11的温度。
