A package structure includes a flexible-rigid PCB and a chip. The flexible PCB includes a flexible PCB, a glue piece and an outer trace layer. The flexible PCB includes two bending portions and a fixing portion connected between the two bending portions, and includes an insulating layer and an inner trace layer formed on the insulating layer. The glue piece is adhered to the fixing portion. The outer trace layer is adhered to the glue piece and includes conductive pads. The fixing portion, the glue piece and the outer trace layer form a rigid portion, the bending portions form flexible portions. The chip is packaged on the rigid portion and includes electrode pads electrically connected to the conductive pads.
