Summary:PROBLEM TO BE SOLVED: To provide a sheet lid in which the power of a required beam is not reflected on a metal lid when it is irradiated with a laser beam for the purpose of sealing, and the reflected beam causes no damage to a sealing unit, the circumference of a part irradiated with a beam, the lid itself or the case itself. SOLUTION: A piezoelectric component is contained in an insulating case having an opening and a sheet lid seals the opening in the insulating case and the circumferential edge thereof in an enclosed atmosphere. The surface of the lid is roughened at least around the edge. COPYRIGHT: (C)2004,JPO
