1.8mmである。 The metal cap 61 of the cylindrical ceramic capacitor shown in FIG. 1 consists of a cylindrical portion 13 and a bottom portion 15. A concave portion 18 is provided in the bottom portion 15 in the shape of a mortar. Note that a protrusion 17 is provided on the inner peripheral surface of the cylindrical portion 13. A pair of metal caps 61
The capacitor element 20 to which the capacitor element 20 is fitted is made of a ceramic body 21 made of barium titanate-based, strontium titanate-based, titanium oxide-based, etc. material, and coated with, for example, known silver paint on the inner peripheral surface 22 and outer peripheral surface 23 of the ceramic body 21, and then baked. By attaching the inner electrode 24 and the outer electrode 25 with a thickness of about 10 μm, for example, the outer diameter is 1.78 mm and the length is 1.78 mm. It is 5.4mm. In addition, since the thickness of electrodes 24 and 25 is 10μ, electrode 2
The outer diameter of the capacitor element 20 formed with 4 and 25 is
It is 1.8mm.

できる。 Since the magnetic capacitor shown in FIG. 1 does not have lead wires, it is impossible to hold the magnetic capacitor with lead wires during or after manufacture. However, since the recesses 18 are provided, an unfinished or completed porcelain capacitor can be securely and easily held by inserting a pair of holding rods 62 into the respective recesses 18 of a pair of metal caps 61 as shown in FIG. It is possible to do so. For this reason, the sealing layer 26, the covering insulating layer 27, the color code colored layer 28 shown in FIG.
etc., can be formed by holding the magnetic capacitor with a holding rod 62 and rotating the magnetic capacitor together with the holding rod 62, as shown in FIG. In addition, this ceramic capacitor is connected to a printed circuit board 6 as shown in FIG.
When the metal cap 61 is bonded to the wiring conductor 64 of No. 3 with solder, the recess 18 can be used for transportation.
