A printed circuit board has a conductor path applied to a substrate having an electrically insulating surface, the conductor path preferably being constructed in the shape of a meander and containing connection areas with holes to which small contact plates are applied for the purpose of later bonding with connection leads. The small contact plates are applied in a hard soldering process with the aid of solder paste to the connection areas of the conductor paths and to the surface area of the substrate surface which is made of ceramic and exposed by the holes. It is consequently possible, dispensing with so-called bonding wires, to directly connect connection leads or bonding lugs electrically with the conductor path and mechanically with the printed circuit board. The printed circuit board is preferably designed as a measuring resistor, wherein the conductor path is applied as a resistance layer of platinum or platinum group metal in a thin film process to a small ceramic plate of aluminum oxide. The small contact plates are preferably made of nickel or a nickel-iron alloy, whereby a good stability results at high temperatures.
