An expansion valve for a refrigerant cycle has an orifice passage portion, a valve body, a spring member and a deformation portion. The orifice passage portion is configured for decompressing and expanding a high pressure refrigerant into a low pressure refrigerant. The valve body is disposed to open and close the orifice passage portion so that a flow rate of the low pressure refrigerant flowing into a low pressure passage portion is controlled in accordance with a valve opening degree. The spring member is disposed between the valve body and the deformation portion for applying a biasing force to the valve body. The deformation portion is plastically deformable in a direction parallel to an expansion and contraction direction of the spring member by applying an external force.
