Abstract: An LED indicator 4 connected to industrial machinery including an inverter 1, includes: an LED substrate 8 into which a display control signal according to a state relating to the industrial machinery is input; and a plurality of displays 31, 32, and 33 configured to display in a lighting state corresponding to a state of the industrial machinery, on the basis of the display control signal input by the LED substrate 8. The plurality of displays 31, 32, and 33 each include a partially circular-arc shape, and are generally arranged in an approximately annular shape. The plurality of displays 31, 32, and 33 include the two displays 31, 32 that generally configure a half ring at one side of the approximately annular shape, and the one display 33 that generally configures a half ring at the other side of the approximately annular shape.
