    Abstract: A luminescent light source includes: a light-emitting element ( 1 ); a substrate ( 2 ) including a conductor pattern ( 4 ); and a phosphor layer material ( 3 ) containing a phosphor and a light-transmitting base material. In the luminescent light source, the light-emitting element ( 1 ) is connected to a conductor pattern ( 4 b), and the phosphor layer material ( 3 ) covers the light-emitting element ( 1 ). Further, at least the light-transmitting base material in the phosphor layer material ( 3 ) is disposed between the light-emitting element ( 1 ) and the substrate ( 2 ). Thus, a luminescent light source can be provided that allows a gap between a light-emitting element such as a LED bare chip or the like and a substrate to be eliminated, thereby obtaining output light with even chromaticity and achieving high luminous efficiency.
