In order to obtain a high resistance I1α of Ω/cml' or more, it is necessary to suppress the amount of various pigments that become resistance components as much as possible, which makes it difficult to uniformly disperse the resistance components, and Since the probability of comrade-like contact also becomes unstable, there is a problem that one-point variation in resistance value is to be accounted for, and the reproducibility of the resistor paste becomes extremely poor.
本発明の目的
そこで本発明は］二連する従来からの問題点を解決し、
４１Ｌ抗仙のバラツキが非常に小さく、しかも再現性

の高抵抗の抵抗器が得られる。To prepare a resistance paste using the fluorinated carbon, for example, the fluorinated carbon can be used in a thermosetting resin or glass frit.
Disperse carbonized carbon. Then, this resistance paste is applied to an alumina substrate, etc., in a predetermined pattern and coating thickness by means such as screen printing, and then dried and baked by performing the necessary treatments to achieve a predetermined high resistance. resistor is obtained.
乾燥及び焼付は等の熱処理工程は、５００″Ｃ以ドの温

ーホンが分解してしまうからである。Heat treatment steps such as drying and baking are carried out at a temperature of 500°C or higher. This is because the fluorinated carphone decomposes at temperatures higher than 500°C.
従って フン化カーホンを分散させる前記カラス質フリ
ットは、融点が５００°Ｃ以下の低融点のカラス質フリ
ットを用いることとなる。Therefore, as the glass frit in which the fluorinated carphone is dispersed, a glass frit with a low melting point of 500° C. or lower is used.
この場合、抵抗成分たるフン化カーホンが、従来用いら
れていたカーボンや酸化ルテニウム等に比べて非常に高

させることが可能である。In this case, since the fluorinated carphone, which is a resistance component, exhibits a much higher resistivity than conventionally used carbon, ruthenium oxide, etc., it is possible to significantly increase the amount added than conventionally.
このため、熱硬化性樹脂またはガラス質フリットに対す

良好になる。Therefore, the dispersion of fluorinated carbon in the thermosetting resin or glassy frit becomes uniform, and at the same time, the probability of contact between fluorinated carbons is stabilized, the variation in resistance value is reduced, and the reproducibility as a paste is improved. Becomes very good.
