Title:
低抵抗抵抗器およびその製造方法
Document Type and Number:
Japanese Patent JP4292711
Kind Code:
B2
Abstract:
The present invention relates to resistors used for detecting current in a current-carrying circuit as a voltage, and aims to provide a resistor, which assures highly accurate measurement of resistance even if the measuring point is not precisely placed. To obtain the above purpose, the resistor of the present invention comprises a sheet metal resistor element (111) and separate metal terminals (112) and (113) electrically connected to both ends of the sheet resistor element (111). These terminals (112) and (113) have their entire surface coated with a metal (115) having a low melting point. With the above configuration, resistance of the terminals can be made smaller than that of the resistor element. This enables a reduction in the proportion of resistance of the terminals in the entire resistor, allowing its effect on the fluctuation of resistance due to deviation in measuring points of a resistance measuring terminals to be ignored.
