Abstract
A less costly bulb-shaped fluorescent lamp with improved assembly efficiency is provided which prevents the impairment of product quality due to the change in color of a holder or the slipping off of a fluorescent tube from the holder decreased in resin strength. The fluorescent lamp includes a set of fluorescent tubes, filament coils disposed at both ends of each fluorescent tube, a starter circuit for activating the fluorescent tubes, a holder for retaining the fluorescent tubes, and a case containing the starter circuit. The holder includes holes for receiving the fluorescent tubes, and a recess defined in a central portion of the holder and extended in the opposite direction of the fluorescent tubes.
