The edge section of the fifth glass cloth is affixed to the rear surface of the base plate using an adhesive, and the first through fourth glass cloths are fastened using staples. In other words, the first glass cloth and the base plate are fixed using an adhesive, and this adhesive is prevented from melting by the five sheets of the first through fifth glass cloths. The adhesive that fixes the edge section of the fifth glass cloth at the other surface of the base plate is prevented from melting by the five sheets of the first through fifth glass cloths and the base plate.
