Abstract:
Disclosed is a substrate on which an element is to be mounted, which has good anti-sulfuration properties. Specifically disclosed is a substrate (1) on which an element is to be mounted, which comprises: a low-temperature co-fired ceramic (LTCC) substrate (2); a thick film conductor layer (3) comprising a metal component mainly composed of silver and formed on at least one main surface of the LTCC substrate (2); and a plated layer (4) composed of a conductive metal and formed on the thick film conductor layer (3). The thick film conductor layer (3) has a smooth surface and is embedded in the LTCC substrate (2) so that the height level of the aforementioned surface of the thick film conductor layer (3) can become almost the same as the height level of the aforementioned main surface of the LTCC substrate (2).
