A method for manufacturing a semiconductor package includes disposing a semiconductor chip having contact pads, and a connection structure around the semiconductor chip on a supporting substrate, with the contact pads facing the supporting substrate, forming an encapsulant encapsulating the semiconductor chip and the connection structure on the supporting substrate, embedding a wiring pattern having a connection portion in the encapsulant, the connection portion having a connection hole, forming a through hole penetrating the encapsulant in the connection hole, the through hole exposing a portion of an upper surface of the connection structure, and forming a conductive via in the through hole, the conductive via connecting the wiring pattern to the connection structure.
