To suppress reduction of capacitor characteristics in environments of high temperature and humidity.SOLUTION: A solid electrolytic capacitor includes a capacitor element having an anode having a dielectric oxide film, a cathode, a separator disposed between the anode and the cathode, and a solid electrolyte layer formed on the dielectric oxide film. By forming an outer layer including a metal oxide on the capacitor element, a solid electrolytic capacitor with excellent heat and moisture heat resistance and a manufacturing method for the same can be provided.SELECTED DRAWING: Figure 1 【課題】温度や湿度が高い環境において、コンデンサの特性低下を抑制する。【解決手段】誘電体酸化皮膜を有する陽極と、陰極と、前記陽極および前記陰極の間に配置されたセパレータと、前記誘電体酸化皮膜上に形成された固体電解質層とを有するコンデンサ素子を備えた固体電解コンデンサにおいて、前記コンデンサ素子上に、金属酸化物を含む外層部を形成することで、耐熱性と耐湿熱性に優れる固体電解コンデンサ及びその製造方法を提供できる。【選択図】図１
