Abstract:
1. A light-emitting device mounting substrate comprising: a base body which mounts thereon a light-emitting device; a first electrically conductive path formed within the base body, one end of the first electrically conductive path being electrically connected to a first electrode of the light-emitting device, and the other end thereof being led out to a surface of the base body; and a second electrically conductive path formed in the base body, one end of the second electrically conductive path being electrically connected to a second electrode of the light-emitting device, and the other end thereof being formed on the surface of the base body, wherein the first electrically conductive path includes a plurality of electrical conductors which are joined to the first electrode of the light emitting device, a total area of joint region between the first electrode of the light-emitting device and each of a plurality of the electrical conductors is set to be larger than the total area of joint region between the first electrode of the light-emitting device and the base body, and the first electrically conductive path is made smaller in thermal resistance than the second electrically conductive path.
