An LED light bulb includes a light source unit. The light source unit includes an LED light emitting element for emitting light and a reflecting plate on which a part of the light emitted from the LED light emitting element is incident. The reflecting plate changes a direction of the part of the light so that the direction of the part of the light is inclined from a direction of an optical axis of the light emitted from the LED light emitting element toward a plane vertical to the direction of the optical axis.
