Abstract
A package structure is provided, including a first insulating layer, a second insulating layer, a third insulating layer, and a chip. The second insulating layer is disposed on the first insulating layer, the chip is disposed in the second insulating layer, and the third insulating layer is disposed on the second insulating layer. The heat conductivity of the second insulating layer is lower than the heat conductivity of the first insulating layer, and the hardness of the second insulating layer is lower than the hardness of the first insulating layer.
