A manufacturing method of a package structure is provided. Firstly, a substrate having a surface is provided. Next, a chip is disposed on the surface of the substrate. Then, a packing material layer is formed on the surface of the substrate. Next, a thin film is pasted on the packing material layer. Then, the substrate and the packing material layer are thoroughly cut along a cutting line around the chip by a first cutting blade but the thin film is not cut thoroughly. Next, the substrate is thoroughly cut along at least a part of the cutting line by a second cutting blade but the packing material layer is not thoroughly cut such that a part of the packing material layer is exposed. The width of the second cutting blade is larger than the width of the first cutting blade.
