シャント抵抗器
Document Type and Number:
Japanese Patent JP6876731
Kind Code:
B2
Abstract:
To provide a shunt resistor capable of surely notifying a user of a resistance value.SOLUTION: A shunt resistor comprises: a pair of electrode plate materials which are separated in a plate surface direction while facing each other; and a resistance alloy plate material which connects the pair of electrode plate materials and has a predetermined preset resistance value. On a surface of the resistance alloy plate material, a visible character string pattern is provided which is formed by laser processing and indicates the preset resistance value of the resistance alloy plate material. A surface area and shaving depth of the character string pattern are set in such a manner that the resistance alloy plate material has the preset resistance value.SELECTED DRAWING: Figure 1
