PROBLEM TO BE SOLVED: To provide a shunt resistor capable of surely notifying a user of a resistance value.SOLUTION: The 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 a 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 【課題】抵抗値を使用者に確実に知らしめることができるシャント抵抗器を提供する。【解決手段】本発明に係るシャント抵抗器は、互いに対して板面方向に離間された一対の電極板材と前記一対の電極板材を連結し且つ所定の設定抵抗値を有する抵抗合金板材とを備えている。前記抵抗合金板材の表面には、レーザー加工によって形成され且つ前記抵抗合金板材の設定抵抗値を示す視認可能な文字列パターンが設けられており、前記抵抗合金板材が設定抵抗値を有するように前記文字列パターンの表面積及び削り取り深さが設定されている。【選択図】図１
