The invention discloses an electronic expansion valve. The electronic expansion valve comprises a valve seat (1) and a valve rod (2), wherein the valve seat (1) is provided with a valve port (121) inside the cavity of the valve seat; the electronic expansion valve also comprises a motor shell and a motor arranged in the motor shell, wherein the motor drives the valve rod to axially move to regulate the refrigerant flow passing through the valve port; the valve rod (2) comprises a matrix (21) integrally formed by injection-molding non-metallic materials; and the matrix (21) is in contact seal or not in contact with the corresponding position of the valve port (121). The electronic expansion valve has the following beneficial effects that through the structural design, on one hand, the danger that the valve rod (2) is loosened and disconnected due to vibration can be avoided, and on the other hand, the sealing property of the valve rod (2) can be improved.
