PROBLEMS TO BE SOLVED: To identify the type and distillation properties for light oils having various compositions different from each other in distillation properties in an accurate and rapid manner. MEANS FOR SOLUTION: A pulse voltage is applied for a predetermined period of time to a liquid type identification sensor heater comprising a heater and an identification liquid temperature sensor provided in the vicinity of the heater; the light oil to be identified is heated by the heater; and the liquid type is identified with a voltage output difference V0, corresponding to a temperature difference between the initial temperature and the peak temperature of the identification liquid temperature sensor.

[Problem] It is an object to provide a lead frame, an electronic device provided with a lead frame, a method of producing a lead frame, and a method of producing an electronic device provided with a lead frame that has been produced by the method of producing a lead frame, in which a lead frame is not corroded, a mechanical strength of the lead frame is not lowered, it is not necessary to carry out the conventional plating processing steps composed of two stages, the processes are simple, a cost is lower, and a large amount of waste liquid such as plating processing liquid is not generated, thereby preventing an environment from being affected. [Means for Resolution] A lead frame comprises an outer lead part and an inner lead part, and a plating is carried out to at least a part of at least any one of the outer lead part and the inner lead part.
