Provided is a color light therapy device. The color light therapy device includes: a body that is used by being attached to a color light therapy portion of a human body by using a double-sided adhesive tape, a hydrogel pad, or an air suction plate, and includes a printed circuit board (PCB) that supplies driving power to a light source that emits color light in a given wavelength range to perform color light therapy on the human body and a power jack that is connected to the PCB of the body through an electric wire. Since a user may use the color light therapy device by connecting the power jack to a mobile phone, a PC, a laptop, a tablet PC, a smartphone, a personal digital assistant (PDA), a vehicle, or a socket at home while carrying the color light therapy device, anyone may conveniently use the color light therapy device to perform color light therapy on the human body without exchanging or charging a battery.
