In '5, wiring was constructed by providing a multilayer conductor layer 2 and an insulator layer 3 on a ceramic substrate 1, and furthermore, a thick film material layer 4 constituting a resistor element, a capacitor element, etc. was formed as a terminal conductor layer. There is a structure provided so as to be connected to the conductor layer 2 via the conductor layer 5. Such a circuit board is manufactured through the following manufacturing process.

First, on a ceramic raw sheet before sintering that will become the ceramic substrate 1, material layers that will become the conductor layer 2 and the insulator layer 3 are printed in multiple layers by screen printing to form a multilayer circuit pattern, and then the same After printing a material layer that will become the terminal conductor layer 5, this is sintered to form a ceramic ivy multilayer board consisting of the ceramic substrate 1, the conductor layer 2, the insulator layer 3, and the terminal conductor layer 5. do. Generally, as the ceramic substrate 1, a material containing AI and O8 as the main components is used, so the temperature during sintering in the above-mentioned process needs to be as high as 15008C to 1600C.
For this reason, high melting point metals such as W, Mo, Mn, etc. are used as materials for forming the conductor layer 2 and the terminal conductor layer 5. Further, since these metals are easily oxidized at high temperatures, the sintering in the above-mentioned process is performed in a reducing atmosphere containing H and gas.

Next, the ceramic multilayer board formed by the above-described process is completed as a circuit board by printing a thick film material layer 4 constituting resistors, elements, etc. on its surface, and then heat-treating it. This heat treatment step is performed on the surface V of the ceramic multilayer substrate.
It is important to prevent the exposed terminal conductor layer 5 from being oxidized. For this reason, the thick film material layer 4 should be made of a material that is hard to reduce and can be fired in a neutral atmosphere, or It is necessary to use a material that can be heat-treated at low temperatures, such as a conductive substance such as carbon powder or Ag powder dispersed in a resin such as epoxy, and there are significant restrictions on the material used for the thick film material layer 4. In addition, when forming the thick film material layer 4 using a generally commercially available thick film material for firing in air, the firing temperature is a high temperature of 500 ° C. or higher.
In order to prevent oxidation of the terminal conductor layer 5 in the above-mentioned ceramic multilayer substrate, measures such as protecting these parts by applying Ni plating are taken. However, in this case as well, non-ohmic connection resistance is generated between the thick film material layer 4 constituting the resistor element, capacitor element, etc. and the Ni plating layer during firing.
