To obtain a portable electronic equipment suppressed in temperature rise at the part that an operator touches for a long time such as a palm rest.

A device and a component which become hot in operation are arranged except below a palm rest part 20, e.g. a keyboard 16. The device which becomes hot in operation is, for example, a CPU(central processing unit) 28, a hard disk drive 30, etc. A battery 34 is relatively small in temperature rise, so it can be arranged below the palm rest part 20.
