摘要

An illumination light source includes: a light-transmissive globe (10); a light-emitting module (20); a drive circuit (50) for causing the light-emitting module (20) to emit light; and a pedestal (45) which includes: a support (30) for fixing the light-emitting module (20) at a predetermined position inside the globe (10); a mounting (40) for holding the support (30); and a heat dissipation portion (46), wherein the heat dissipation portion (46) is between the drive circuit (50) and an area (44) for disposing the support (30) on a main surface (40a) of the mounting (40) which is on a side where the light-emitting module (20) is provided, and has a surface which forms an angle with a back surface (40b) of the mounting (40) on a side opposite the main surface (40a).
