1. Electronic equipment allowed to be used in a medical site undergoing a sterilizing treatment using water vapor in an autoclave apparatus, comprising:
an enclosure having a front surface and a back surface opposite to the front surface;
a substrate arranged in an internal space of the enclosure;
an electronic circuit component mounted on the substrate;
a first heat insulating layer formed along the enclosure;
a first heat release mechanism allowed to discharge heat from an internal space of the first heat insulating layer to outside of the enclosure;
a second heat insulating layer separating from the first heat insulating layer and formed to surround the substrate and the electronic circuit component;
a second heat release mechanism allowed to discharge heat from a space surrounded by the second heat insulating layer to a gap between the first heat insulating layer and the second heat insulating layer;
wherein the first heat release mechanism has a first heat absorbent surface exposed to an inside of the first heat insulating layer and a first heat release surface being opposite to the first heat absorbent surface and exposed to an outside of the enclosure, and
the second heat release mechanism has a second heat absorbent surface exposed to an inside of the second heat insulating layer and a second heat release surface being opposite to the second heat absorbent surface and exposed to an outside of the second heat insulating layer.
