本発明は、特願昭５９−２６７３４６号と異なりセラミ
ック基板に開孔を設は金属素子を嵌合させるものではな
いので、開孔によるセラミック基板の機械的強度劣化も
なく、また、金属素子を嵌合させるという工程もないの
で実用上極めて優れている。Unlike Japanese Patent Application No. 59-267346, the present invention does not provide openings in a ceramic substrate to fit metal elements, so there is no deterioration in the mechanical strength of the ceramic substrate due to the openings, and metal elements cannot be fitted into the ceramic substrate. Since there is no fitting process, it is extremely superior in practical terms.
さらに、本発明はセラミック基板上に蒸着やスパッタリ

金属膜が薄すぎるために接続子を直接溶接できない等の
問題もなく、極めて実用性に富む。Furthermore, unlike the method in which a thin metal film is attached on a ceramic substrate by vapor deposition or sputtering, the present invention has the problem that the metal film cannot withstand the heat process when firing the resistor material, and that the metal film is too thin and cannot be connected. There are no problems such as not being able to weld the parts directly, and it is extremely practical.
また、本発明ではセラミック基板と金属片の接合工程と
抵抗材の焼成工程を同時にできるので、経済的にも優れ
ている。Furthermore, the present invention is economically advantageous because the process of bonding the ceramic substrate and the metal piece and the process of firing the resistive material can be performed at the same time.
