To provide natural air cooling type information equipment for radiating heat in the main body of information equipment such as portable terminal equipment by using a display part side case body whose heat radiating performance is increased.

In this information equipment having a heating element arranged inside the main body of the information equipment and a display part side case body mounted on the main body of the information equipment so as to be openable and closeable in which a display device is arranged, a fluid refrigerant container in which a fluid refrigerant is hermetically sealed is arranged in the display part side case body, and one end of a heat transferring device constituted of high thermal conductive materials is connected to the heating element in the main body so that heat transfer can be performed, and the other end of the heat transferring device is connected to the fluid refrigerant in the fluid refrigerant container so that heat transfer can be performed.
