<P>PROBLEM TO BE SOLVED: To provide a light-emitting device in which electrical connection of a light-emitting element and an electrode can be ensured with no practical problem by both a soldering method and a connection method using a connector, and to provide a luminaire having the light-emitting device. <P>SOLUTION: A light-emitting device 1 has a plurality of LED chips 11, electrode lands 17 (17a, 17k) for soldering connected electrically therewith, and electrode lands 19 (19a, 19k) for connector connection on a ceramic substrate 3. The electrode lands 17 for soldering are formed of a material containing a first conductive material having a solder diffusion prevention function, and the electrode lands 19 for connector connection are formed of a material containing a second conductive material having an oxidation prevention function. <P>COPYRIGHT: (C)2012,JPO&INPIT |
