摘要： A data generating device includes: a storage; and a controller. The storage is configured to store a plurality of sets of machining condition information in association with respective ones of a plurality of sets of foil information. Each of the plurality of sets of machining condition information specifies a machining condition on irradiation of a laser beam from a laser machining device onto a surface of a workpiece on which a metal foil is placed. Each of the plurality of sets of foil information specifies composition of the foil. The controller is configured to perform: receiving input information specifying composition of a target foil to be subjected to the irradiation of the laser beam as one set of foil information; and identifying one set of machining condition information corresponding to the one set of foil information from the plurality of sets of machining condition information stored in the storage.

摘要： A shunt resistor according to the present invention includes a pair of electrode plates spaced apart from each other in a plate surface direction and a resistive alloy plate that connects the pair of electrode plates and that has a predetermined set resistance value. A surface of the resistive alloy plate is provided with a visually recognizable character string pattern that is formed by laser processing and that indicates the set resistance value of the resistive alloy plate, and a surface area and a carving depth of the character string pattern are set in such a manner that the resistive alloy plate has the set resistance value.
