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 provided over a heat-generating component to conduct heat thereof, a heat absorption area to absorb the heat of the heat-generating component through the heat conducting spacer and a heat conduction obstructing area provided on a heat conduction path between the heat absorption area and the palm rest to reduce a cross-sectional area of the heat conduction path. Accordingly, heat conduction from the high-temperature heat generating component to the palm rest is restricted, and thus the temperature of the palm rest can be limited.

An extension device is engaged in a connector provided on one side of a lower case of a cabinet of an PIP apparatus PI. An adjustable foot is provided on the bottom surface to adjust the extension device and the cabinet in height. Therefore, the cabinet can be horizontally placed on a plane. When the extension device is approximately equal in height to the lower case , the adjustable foot is retracted into the lower case . Therefore, the thickness of the PIP apparatus PI can be minimized.
