    • A solid electrolytic capacitor includes a capacitor element including a capacitance forming portion; an encapsulating resin with which the capacitance forming portion is coated; an anode terminal and a cathode terminal that are provided such that at least a part thereof is outside the encapsulating resin; and a lead. The capacitor element includes an anode, and a dielectric layer and a solid electrolytic layer that are laminated on a portion of the anode in this order. The lead is electrically connected to the solid electrolytic layer. The surface of at least one component selected from the anode and the lead has roughness in at least one connection portion selected from a connection portion between the anode and the anode terminal and a connection portion between the lead and the cathode terminal.
    • 固体电解电容器包括:电容元件,其包括电容形成部; 涂覆电容形成部分的封装树脂; 阳极端子和阴极端子,其至少一部分设置在封装树脂外部; 和领先。 电容器元件包括依次层压在阳极的一部分上的阳极和电介质层和固体电解质层。 引线与固体电解质层电连接。 从阳极和引线中选择的至少一个部件的表面在从阳极和阳极端子之间的连接部分和引线和阴极端子之间的连接部分中选择的至少一个连接部分中具有粗糙度。
