PROBLEM TO BE SOLVED: To provide a supercooling degree control type expansion valve which enables arbitrary alteration of a supercooling degree to be controlled to be a prescribed one and can meet a wide variety of uses. SOLUTION: A valve disk 8 for opening and closing a refrigerant passage is disposed opposite to a valve seat 6, in a state of being biased from the downstream side by a biasing means 14, so that a refrigerant be expanded adiabatically and sent to an evaporator in the condition that the supercooling degree on the upstream side of the valve seat 6 becomes a prescribed one. In the supercooling degree control type expansion valve thus constituted, a solenoid 10 controlling the biasing force of the biasing means 14 by electromagnetic power is provided.
