An object of the invention is to provide a smaller semiconductor device of which the manufacturing process is simplified and the manufacturing cost is reduced. Furthermore, an object of the invention is to provide a semiconductor device having a cavity. A device element 3 is formed on a front surface of a semiconductor substrate 4, and a sealing body 1 is attached to the semiconductor substrate 4 with an adhesive layer 6 being interposed therebetween. A main surface (a back surface) of the sealing body 1 which faces the semiconductor substrate 4 is curved inward, and there is a given space (a cavity 2) between the sealing body 1 and the semiconductor substrate 4. Since the back surface of the sealing body 1 is curved, the sealing body 1 is used as a planoconcave lens (a reverse direction) as well as a sealing member for the device element 3. |
