Provided is a mounting component for an optical fiber that allows a laser device and an optical fiber to be aligned with higher precision while providing protection for the laser device mounted on a substrate. The a mounting component is a component formed from silicon for optically coupling a laser device to an optical fiber by being bonded to a mounting substrate on which the laser device is mounted, and includes a groove portion for fixedly holding the optical fiber so that a core of the optical fiber is positioned at a predetermined depth with respect to a bonding surface to be bonded to the mounting substrate, and a recessed portion, formed continuous with the groove portion, for accommodating the laser device, wherein a thickness of the mounting component, measured in a direction perpendicular to the bonding surface, is chosen so that a position of the laser device can be detected using an infrared transmission image when the laser device is accommodated in the recessed portion by placing the bonding surface in contact with the mounting substrate.
