In the figure, the same parts as those in the above-mentioned conventional example are designated by the same reference numerals, and detailed description thereof will be omitted. FIG. 1 is an exploded perspective view of a circuit device. In the figure, like the insulating sheet 4 described above, 14 is an insulating sheet having a role of preventing the circuit component 2h assembled on the lower surface of the circuit board 2 from making conductive contact with the metal plate 1a of the stem 1. This insulating sheet 14 has notches 14a-1
4c is formed and has a protrusion 14d, which is attached to the stem 1 as shown in FIG. FIG. 2 is a view showing a state in which the insulating sheet 14 is attached to the stem 1. There are a plurality of rows of external terminals 1c on both sides of the insulating sheet 14, and the external terminals 1c directly project onto the insulating sheet 14 without penetrating each hole as in the conventional case. The projecting portion 14d of the insulating sheet 14 is located between the external terminals, and is prevented from separating from the stem 1 in the XX 'direction with the other projecting portion 14e. From the state shown in FIG. 2, the circuit board 2 is mounted and the cap 3 is welded in the same manner as in the above-described conventional example to form the circuit device as shown in FIG.
