A recess is formed in the region where the rough surface portion 14 should be formed on the principal surface of the wiring board 11. Consequently, a surface of the rough surface portion 14 is slightly uneven in conformity with the uneven surface of the region where the rough surface portion 14 should be formed, thereby enhancing the contact with the sealing resin 13 more.
