Title
(EN) ELECTROLYTIC CAPACITOR AND PRODUCTION METHOD THEREFOR
(FR) CONDENSATEUR ÉLECTROLYTIQUE ET SON PROCÉDÉ DE PRODUCTION
(JA) 電解コンデンサおよびその製造方法
Abstract
(EN)
This electrolytic capacitor is provided with a capacitor element which comprises: an anode body; a dielectric layer formed on the surface of the anode body; and a solid electrolyte layer that covers at least a part of the dielectric layer. The anode body has fine pores. The capacitor element is further provided with silica particles that are disposed within the fine pores so as to attach to the dielectric layer covering the anode body. The solid electrolyte layer covers the silica particles.

L'invention concerne un condensateur électrolytique comprenant un élément condensateur qui comprend : un corps d'anode ; une couche diélectrique formée sur la surface du corps d'anode ; et une couche d'électrolyte solide qui recouvre au moins une partie de la couche diélectrique. Le corps d'anode présente des pores fins. L'élément condensateur comprend en outre des particules de silice qui sont disposées à l'intérieur des pores fins de façon à se fixer à la couche diélectrique recouvrant le corps d'anode. La couche d'électrolyte solide recouvre les particules de silice.
(JA)
電解コンデンサは、陽極体と、陽極体の表面に形成された誘電体層と、誘電体層の少なくとも一部を覆う固体電解質層と、を含むコンデンサ素子を備える。陽極体は細孔を有し、コンデンサ素子は、細孔内において、陽極体の表面を覆う誘電体層に付着したシリカ粒子をさらに備える。固体電解質層が、シリカ粒子を覆っている。
