This invention provides a capacitative element that comprises a dielectric layer provided between a first electrode layer and a second electrode layer and enables the capacitance to be changed by an externally applied voltage. The dielectric layer is formed of a perovskite oxide represented by a chemical formula (A2+B4+O3)x-(A2+(C2+ La présente invention concerne un élément capacitatif qui comprend une couche diélectrique prévue entre une première et une seconde couche d'électrodes et permet de modifier la capacitance avec une tension appliquée en externe. La couche diélectrique est constituée d'un oxyde de pérovskite représenté par une formule chimique (A2+B4+O3)x-(A2+(C2+
