The patterns 2 and 3 are connected to the door window 16 by the terminal portions 2b and 3c and the connecting portion 17, and are formed on the strip-shaped member F2 made of the second metal plate, and fixed to be connected to each other. The contacts 4 and 5 are coupled to the door window 16 by the terminal portions 4b and 5b.

Next, the strip-shaped member F which consists of metal plates comprised in this way is cut | disconnected in the line S1 in the strip | belt-shaped member F1 which consists of a 1st metal plate, as shown in FIG. ) Are separated from each other at the central portion, and are cut at the line S2 in the strip-shaped member F2 made of the second metal plate, so that the fixed contacts 4, 5 are separated from each other, and at the line S3. The strip | belt-shaped member F1, F2 which consists of a 1st, 2nd metal plate is cut | disconnected and cut | disconnected.

In this first molding step, the conductive patterns 2 and 3 and the fixed contact 4 are plural places, and the fixed contact 5 is pressed into the mold from the top and the bottom at one place in the center. Since it is shape | molded, the hole 1g is formed.

In this first molding step, the peripheral edge portions of the conductive patterns 2 and 3 and the fixed contact 4 are adjacent to each other so that the step D is almost the same as the plate thickness of the strip-shaped member 16 made of a metal plate. Have been deployed.

However, when disposed close to 0.5 mm or less on the same surface, the space between the plate thicknesses is narrow, the resin is difficult to flow, and the resin is not filled, so-called short problem occurs, but in this embodiment, the plate thickness and Since they are arranged with the same step D and do not face each other in the height direction, it is possible to reliably fill the resin, so that the distance between them is about 0.5 mm, that is, a band-shaped member made of a metal plate ( Both of them can be reliably insulated even in a small size of about 4 times or less (the plate thickness is about 0.12 mm).

Further, in the production of the insulating base body 1, the bending of the conductive patterns 2 and 3 and the fixed contact 4 and 5 caused by the hydraulic pressure of the synthetic resin is achieved by making the two steps of the first and second molding steps. By making the hole smaller or blocking the holes 1g to prevent the yellowing of the contact portion and the flux rise at the time of soldering or separation, it is easy to produce a complicated mold.

In the present embodiment, the step D of the peripheral edge portions adjacent to each other between the conductive patterns 2 and 3 and the fixed contact point 4 is substantially the same as the plate thickness of the strip-shaped member 16 made of a metal plate. However, it may be less than that, or may overlap in the planar direction, in which case it can be further miniaturized.
