ABSTRACT:
The present invention provides an information processing apparatus that may be designed in small and thin size and a small and thin CPU module that has a nigh heat releasing effect and is suitable therefor. The CPU module includes a processor, a connector to be electrically connected to the outside, a system control circuit for controlling transfer of a signal between the processor and the connector, and a printed board on which the processor, the connector and the system control circuit are mounted. The CPU module further provides a heat release plate one side of which is pasted with the printed board and the other side of which is substantially planar. The printed board has a cavity formed therein so that the processor may be fitted in the cavity in a bare-chip state. One side of the bare chip is jointed with the heat release plate.
