PROBLEM TO BE SOLVED: To provide a current measuring analyzer for an electric railcar capable of easily and quickly measuring an electric railcar current, capable of sufficiently coping with rainy weather time, an having no limitation to the size of measuring object. SOLUTION: This current measuring analyzer for the electric railcar is characterized by having a pickup sensor 1 for measuring a DC and AC high voltage large electric current such as the electric railcar current flowing to rails, a portable data recorder 2 for recording data measured by the sensor, a waterproof memory card 5 capable of recording the data recorded in the recorder, and a data analyzer-processor 9 for reading, analyzing and processing the data recorded in the memory card.
