Abstract: More efficient radiation of heat from a point-like light source is enabled, and thinning is promoted, while higher and more uniform brightness of a planar illumination device is accommodated. A radiation path is formed through which the heat generated from the point-like light source is transmitted to a radiator plate made of metal through an electrode terminal of the point-like light source, a land portion of a front side face of an FPC, a through hole of a conductor pattern, and a high heat-conductive resin. The radiation path for efficient radiation from a conductor pattern of the FPC to the radiator plate made of metal is extended, and direct radiation area is sufficiently ensured. Particularly even if a large-current type LED is used for the point-like light source, sufficient radiation effect can be obtained.
