ABSTRACT:
A shield case having openings at both ends is fabricated by drawing a blank and the opening at one end of the shield case is formed at the periphery thereof as a flat annular receiving portion, with a portion intermediate the receiving portion and the case side surface curved with a gentle curvature. A capacitor including a doughnut shaped dielectric unit is disposed inside the shield case contiguous to the receiving portion and a metallic cylinder is provided extending through the aperture of the dielectric unit of the capacitor and the one end opening of the shield case. One electrode is formed on one main surface of the doughnut shaped dielectric unit, while the other electrode is formed on the other main surface of the unit and a lead out electrode is also formed around the aperture on the other main surface of the unit electrically isolated from the said other electrode. A resistor film is formed between the other electrode and the lead out electrode, and electrical connection is made between the metallic cylinder and the one electrode, and an electrical connection is also made between the metallic cylinder and the lead out electrode, while these are mechanically fixed.
