A sensor
package structure is provided and includes a substrate, a sensor
chip disposed on the substrate, a plurality of wires electrically coupled to the substrate and the sensor
chip, a light-permeable layer, and a
colloid formed on the substrate to fix the light-permeable layer. The
colloid covers the wires, a
peripheral portion of the sensor
chip, and lateral surfaces of the light-permeable layer. A top curved surface of the
colloid is partially arranged beside the lateral surfaces. In a cross section of the sensor
package structure, the top curved surface has a reference point spaced apart from one of the lateral surfaces adjacent thereto by 100 μm, a top edge of the top curved surface and the reference point define a connection line, and the connection line and the one of the lateral surfaces have an
acute angle within a range from 25 degrees to 36 degrees.
