Abstract: PURPOSE: To provide an insulation tester which can display measuring data in a histogram. CONSTITUTION: A discrimination device 12 is provided in a measuring part 11 of a main body of an insulation tester which measures the insulation resistance of an object. An insulation resistance value measured by the measuring part 11 is inputted to the device 12, whereby whether the object has good insulation properties or not is judged. At the same time, the device 12 classifies insulation resistance values of good objects every predetermined range in accordance with the size of the values. The insulation tester 10 is further provided with a counter 13 which sums a count of insulation resistance values within each range classified by the device 12 individually, a display device 14 having a histogram display function, and a setting means 15 for preliminarily setting a threshold value (size) for the insulation resistance value to judge good objects by the device 12. After the measurement, counts of the insulation resistance values in every predetermined range from the counter 13 are inputted to the display device 14 as statistic data and displayed in a histogram.
