Abstract:
1. A mounting structure comprising: an injection molded substrate including a resin portion and conductive portions exposed at portions of a surface of the substrate; a surface-mount component positioned on the substrate, and opposite side portions of the surface-mount component are connected to a pair of the respective conductive portions of the substrate at respective connection portions by solder; and a stress relaxation mechanism provided at least under the surface-mount component and being configured to relax stress applied to the solder in response to thermal expansion of the resin portion, the stress relaxation mechanism including: (i) a first hole provided between the connection portions under the surface-mount component, and (ii) a second hole formed in the corresponding conductive portion at a position located laterally of at least one of the connection portions, wherein the first hole and/or the second hole is a through-hole extending through the substrate.
