PROBLEM TO BE SOLVED: To constitute a rectifying element by utilizing the Coulomb blockade phenomenon among quantum dots, using double quantum dots. SOLUTION: The double quantum dot charged type rectifier which comprises two quantum dots performs rectification, by using the Coulomb blockade phenomenon, in a single electron tunneling between quantum dots. The rectifier comprises a first quantum dot 1 and second quantum dot 2, a first tunnel junction 5 for connecting the quantum dot 1 to a source electrode 3, a first capacitive junction 7 which connects the quantum dot 1 to the quantum dot, a second tunnel junction 6 which connects the quantum dot 1 to a drain electrode 4, a third tunnel junction 8 which connects the quantum dot 2 to the source electrode 3, and a second capacitive junction 9 which connects the quantum dot 2 to the drain electrode 4.
