According to one embodiment, a luminaire (1) includes an envelope (12) including a light transmission section, a rectangular substrate (22) provided in the envelope, and a pair of supporting sections (14a, 14b). On one surface of the substrate, plural light-emitting elements (20) are mounted side by side on a line (L') shifted to one side in the width direction of the substrate from a center line (L) extending along the longitudinal direction of the substrate. Electronic components (15) are mounted in positions deviating to the other side in the width direction of the substrate from the line (L'). The pair of supporting sections are provided on the inner surface of the envelope and support both the end sides of the substrate, which are along the longitudinal direction of the substrate. |
