Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an optical repeater and a laser processing device capable of reducing the return light from a processed part, while reducing the possibility of damage on the optical repeater and laser processing device.SOLUTION: The optical repeater that relays the laser light from a laser oscillator to a laser irradiation head for irradiating a processed part with laser light includes a lens for condensing the laser light from a laser oscillator to the end face of a head side optical fiber. The optical axis of the head side optical fiber is inclining to the optical axis of the laser light condensed to the end face of the head side optical fiber.
