An LED module includes: a package having electrodes provided on the outer surface of opposing sidewalls, and a light-emitting element connected to the electrodes and mounted on the package; a base member having a copper metal; an insulating layer stacked on the surface of the base member and having an insulating material; and a conductive wiring pattern connected to the electrodes by soldering and formed on the surface of the insulating layer. The insulating layer has a through-hole formed by removing a part of the section where the package is positioned, and a heat dissipation unit formed by soldering between the back surface of the package and the base member, which face one another with the through-hole interposed therebetween.
