The invention discloses a sensor package and a method for fabricating the same. The sensor package includes: a substrate with an opening; a sensor chip disposed in the opening and electrically connected to the substrate; an encapsulant filling spacing between the sensor chip and the opening so as to secure the sensor chip to the substrate; and a transparent cover attached to the substrate via an adhesive layer, wherein the adhesive layer covers the sensor chip and bonding wires and is formed with an opening for exposing sensor region of the sensor chip. Securing the sensor chip in the opening of the substrate reduces the height of the sensor package, and meanwhile the process cost is reduced by eliminating the need of formation of conductive bumps on the sensor chip or the transparent cover and eliminating the need of specially designed substrate.
