Abstract: In a coil component, an inorganic layer which is provided on a lower surface side of a coil has a thermal conductivity higher than that of a resin layer with which an upper surface of the coil is covered and gaps between windings are filled. As a result, heat transfer from the inside of the coil to the outside is supplemented via the inorganic layer. That is, heat transfer of the coil via the inorganic layer is facilitated, and heat dissipation of the coil component improves.

Abstract: A magnetically actuated MEMS switch 100 includes a first magnetic core portion 120, a first signal line 15, a first contact point 16, a second magnetic core portion 220, a second signal line 25, a second contact point 26, and a first coil portion 111 and a second coil portion 211 serving as a magnetic field applying portion that causes a current to flow in conductor coil to apply a magnetic field to the first magnetic core portion 120 and the second magnetic core portion 220. The first contact point 16 is displaced depending on the presence or absence of a magnetic field applied by the magnetic field applying portion. Connection and disconnection between the first contact point 16 and the second contact point 26 are switched in response to displacement of the first contact point 16.

Abstract: A lower electrode (4) can have an uneven surface structure. An upper electrode (6) can also have the uneven surface structure. A projecting portion of the upper electrode (6) projecting to the lower electrode side is positioned in a gap between projecting portions of the lower electrode (4) and the lower electrode (4) includes Cu as a main component. Young's moduli of a substrate (1), a stress adjustment layer (2), and the lower electrode (4) have a specific relation. Also, corner portions of radii (R1) of curvature positioned inside a projecting portion (4b) have a specific relation.
