Disclosed is an electronic expansion valve which comprises: a valve housing having a first connection unit and a second connection unit, where a line, where fluid flows, is coupled, and having a chamber of which an upper portion is opened; a piston having a channel where the fluid passes and closely attached to the chamber to be lifted; and a driving unit coupled to an upper portion of the valve housing to lift the piston. When the piston is descended to enable the channel to be connected to the first connection unit and the second connection unit, the fluid starts to flow and a flow amount and pressure of the fluid can be easily and accurately controlled.
