Abstract
An electronic heat pump device has an emitter and a collector, stems supporting these components, a spacing retention member for keeping a spacing between the stems constant, and a sealing member for maintaining a vacuum between the stems. The emitter has a first semiconductor substrate and an emitter electrode, while the collector has a second semiconductor substrate and a collector electrode. The emitter electrode and the collector electrode are disposed so as to be opposed to each other with a space interposed therebetween. At least one of the first and second semiconductor substrates is integrally formed with electrically and thermally insulative spacers that keep the space between the emitter electrode and the collector electrode constant.
