A package module includes a circuit board, an electronic component disposed on the circuit board, a frame disposed next to at least one side of the electronic component, and an encapsulant. A gap is formed between the frame and the electronic component. The encapsulant includes a first portion covering at least a part of the circuit board, and a second portion filling into at least a part of the gap. The first portion has a first height relative to the circuit board, and the second portion has a second height relative to the circuit board, in which the second height is greater than the first height.
