Abstract

A clip (22) is provided with an annular supporting section (22a) having an opening section (22c) at an upper section; a fixing section (22b) arranged at the lower section of the supporting section (22a); and two protruding sections (22d) which protrude upward to the side of the opening section (22c) from each end section facing the opening section (22c) of the supporting section (22a). A cold-cathode tube (21), i.e., a line light source, is inserted from the opening section (22c) to the inner side of the supporting section (22a). Since the cold-cathode tube (21), which tends to be removed upward from the supporting section (22a), receives downward force due to the protruding section (22d), the cold-cathode tube (21) is prevented from dropping.
