Zusammenfassung:	To provide a power element which achieves downsizing of an expansion valve while inhibiting deterioration of controllability and can maintain sealability, and to provide an expansion valve using the power element.SOLUTION: A power element includes: an upper lid member; a receiving member; and a diaphragm sandwiched between the upper lid member and the receiving member. The receiving member has: a cylindrical part; and an annular flange part bent in a direction intersecting with the cylindrical part. Cutting is performed at the cylindrical part located adjacent to the annular flange part.SELECTED DRAWING: Figure 2 【課題】制御性の悪化を抑えつつ膨張弁の小型化を図るとともに、シール性を維持することができるパワーエレメント及びそれを用いた膨張弁を提供する。【解決手段】上蓋部材、受け部材、及び前記上蓋部材と前記受け部材との間に挟まれるダイアフラムを含むパワーエレメントは、前記受け部材は、円筒部と、前記円筒部に対して交差する方向に折り曲げられた環状フランジ部とを有し、前記環状フランジ部に隣接する前記円筒部に切削加工が施されている。【選択図】図２
