摘要

PROBLEM TO BE SOLVED: To provide an illumination lamp capable of suppressing a warpage at low cost and with a simple structure.SOLUTION: A translucent cover 3 covers a long substrate 21 where an LED 20 is mounted, a heat sink 22 to which the substrate 21 is attached, and the LED 20 mounted in the substrate 21. The cover 3 is formed into a tubular shape extending in a longitudinal direction, and houses the heat sink 22 in a tubular inside. The cover 3 is formed by a fiber reinforced resin where a glass fiber is mixed to a translucent resin having translucent property.
