A jig for measuring light is provided to measure the light more accurately and to reduce an unnecessary cost due to a damage of a clamp by forming a guide unit instead of the clamp. A jig for measuring light includes a body(100), a recess(200), and an operating unit(300). The recess is formed at top surface of the body. The operating unit is formed at bottom surface of the body. The body is made of a nonconductor such as a resin. The recess is formed to insert and to fix a light emitting diode to measure the light and includes an inclusion unit and an inserting unit. An electrode is formed in an inserting unit to supply power to a guide unit and a light emission diode for preventing the light emission diode from being deviated.
