PROBLEM TO BE SOLVED: To provide an electrode sheet for detecting pressure and a pressure detection module having the same.SOLUTION: An electrode sheet 440 includes an electrode layer and support layers. The electrode layer comprises a first electrode 450 and a second electrode 460, and is used to detect changes in capacitance between the first electrode and the second electrode caused by changes in relative distance between the electrode layer and a reference potential layer (display module 200 or substrate 300) located at a distance from the electrode sheet. The support layers 470b, 471b may be made of a type of material having enough rigidity to maintain a shape of the electrode sheet even when the relative distance between the electrode sheet and the reference potential layer changes.SELECTED DRAWING: Figure 3g 【課題】圧力検出のための電極シート及びこれを含む圧力検出モジュールを提供する。【解決手段】電極シートは４４０、電極層及び支持層を含み、電極層は第１電極４５０と第２電極４６０を含み、電極シートと離隔して位置する基準電位層（ディスプレイモジュール２００又は基板３００）と電極層との間の相対的な距離変化によって変わる、第１電極と第２電極との間の静電容量の変化を検出するのに用いられる。支持層４７０ｂ、４７１ｂは、電極シートの基準電位層との相対的な距離変化が発生しても電極シートの形態を維持する剛性を有する属性材料であってもよい。【選択図】図３ｇ
