PROBLEM TO BE SOLVED: To provide a VEP pad which can be not only reused but also single-used by attaching/detaching the VEP pad freely to/from a conversion board for controlling a power supply to a plurality of LEDs, and to make it possible that a clear brightness difference such as a goggle type, and that the emission period and emission intensity of each LED is individually controlled to make the position identification or the half side visual field stimulation of a pupil possible.SOLUTION: A pad comprises: a flexible printed substrate 6 having a flat-shaped pad part 9, a line drawing part 10 and a print wiring part 5; a plurality of LEDs 7 arranged in the pad part 9 and connected in an independently drivable manner with the print wiring part 5, for emitting a light from a surface side of the pad part 9; a reflector mounted in the pad part 9; and a connector 8 for connecting the print wiring part 5.SELECTED DRAWING: Figure 1 |
