A solid electrolytic capacitor package structure includes a capacitor unit, a package unit and a conductive unit. The package unit includes a package body for enclosing the capacitor unit. The conductive unit includes at least one first conductive terminal and at least one second conductive terminal. The first conductive terminal includes a first core layer and a first enclosing layer. The first core layer has a first top exposed surface exposed from the first enclosing layer, and the first top exposed surface has a first top covering area covered by the package body. The second conductive terminal includes a second core layer and a second enclosing layer. The second core layer has a second top exposed surface exposed from the second enclosing layer, and the second top exposed surface has a second top covering area covered by the package body.
