Abstract: Disclosed in the present invention are a sensor packaging structure and a manufacturing method thereof. The sensor packaging structure includes a protection board, a circuit structure and a filling structure. A front surface of the circuit structure is connected to a first surface of the protection board. A second surface of the protection board is used as a sensing function surface. The filling structure is located on the outer periphery of the circuit structure and connected to the first surface of the protection board. The sensor packaging structure of the present invention uses the protection board as a protection layer of the functional circuit, which can effectively protect the functional circuit of the sensor. Meanwhile, the protection board is first connected to the circuit structure in the manufacturing method to avoid tolerance accumulation, increasing the manufacturing accuracy of the protection layer.
