Abstract
A thin-film device is provided with high reliability that prevents breakage of a thin-film resistance element due to stress caused by expansion of a resin layer. Thin-film resistance elements can be pressed against a substrate with a first constraint thin film that is formed on a resin layer arranged on a resin layer at the opposite side to the substrate so as to overlap with the thin-film resistance elements when seen in the plan view of the device. Therefore, bending stress that is applied to the thin-film resistance elements due to expansion of the resin layers in a high-temperature state can be moderated to thereby prevent breakage of the thin-film resistance elements due to stress caused by the expansion of the resin layers.
