PROBLEM TO BE SOLVED: To provide a micro device applicable to, for example, an amplifying circuit having a memory function, a memory apparatus or an analog switch, etc. by using an electron emission element. SOLUTION: The micro device 10 is provided with a memory part 18 accumulating a charge according to an input voltage Vi, the electron emission element 14 emitting electrons according to the charge accumulated in the memory part 18 and an amplifying part 16 connected with a power source 22 and containing a collector electrode 20 capturing the electrons emitted from the electron emission element 14. At least the atmosphere between the electron emission element 14 and the collector electrode 20 is a vacuum. The electrons emitted from the electron emission element 14 are captured by the collector electrode of the amplifying part 16, which induces a collector current Ic flowing between the collector electrode 20 and the electron emission element 14, and amplification is performed by the collector current Ic.
