PROBLEM TO BE SOLVED: To provide a lamp having a heat radiation structure capable of coping with increase of heating value due to high luminance.SOLUTION: A lamp is provided with a base on which a rod-shape member is installed, a globe of which opening is closed by the base, and an LED module 5 in which an LED 3 is arranged on one of two main surfaces of a mounting substrate 21 and which is supported in the globe as the another of the two main surfaces of the mounting substrate 21 is in contact with the rod-shape member. A concavo-convex processing is applied to a region (X) excluding a portion which is in contact with the rod-shape member, in the another of the two main surfaces of the mounting substrate 21. |
