An expansion valve 1 comprises a prism-shaped body 10, and a valve chamber 20 is formed within the body 10. Refrigerant supplied from a compressor flows into the valve chamber through a passage 22, passes between a valve means 42 and a valve seat 23, and travels toward an evaporator through a passage 24. Refrigerant returning from the evaporator enters the body 10 through a passage 26, and after the refrigerant temperature information is transmitted to the operating shaft 40, the refrigerant flows out through a passage 28 toward the compressor. Passages 22 and 28 open to a first side surface of the body, and passages 24 and 26 open to a second side surface orthogonal to the first surface. Such structure improves the degree of freedom for mounting the expansion valve 1.
