摘要：
There is provided a small-size electronic heat pump device which is low in power consumption and which secures a vacuum gap without use of an additional circuit. The electronic heat pump device includes an emitter 1 and a collector 2. An electrically and thermally insulative spacer section 5 for keeping a space, i.e. vacuum gap G between an emitter electrode 11 and a collector electrode 21 constant is integrally formed in a semiconductor substrate 20 of the collector 2, which makes it possible to maintain the vacuum gap to be a specified space while a back flow of heat is prevented in a simple structure with a reduced number of component parts.
