Abstract: A disclosed solid electrolytic capacitor includes a capacitor element, a lead terminal and a lead terminal that are electrically connected to the capacitor element, and an exterior body that seals a portion of the lead terminal, a portion of the lead terminal, and the capacitor element. The exterior body includes a resin part containing a resin. The resin has a glass transition point Tg of 140° C. or less, where the glass transition point Tg is a temperature of the resin part at which a loss modulus measured by nanoscale dynamic viscoelastic measurement using a nanoindentation method changes from an increasing state to a decreasing state. The hardness of the resin part measured by the nanoindentation method is 0.08 GPa or less in a temperature range from the glass transition point Tg to 260° C. inclusive.
