One end of a cylindrical mount 10 is attached to an end of a cylindrical base 30 that is to be inserted into a socket of a lighting fixture. The end of the mount 10 is rotatable around a central axis of a base 30. A support 40 is attached to other end of the mount 10 so as to rotate integrally with the mount 10. An LED module 51 that includes a plurality of LED chips is attached to the support 40. An end face 43a, on which the LED module 51 is attached, is provided on the support 40. The end face 43a is formed so that the direction of light emitted by the LED chips provided on the LED module 51 is inclined at a predetermined angle with respect to the axial direction of the base 30.
