Abstract: In a coil component, a shield layer is provided after the unevenness of the surface of an element body is smoothened by the surface being covered with an insulating layer. A Cu layer of the shield layer is provided on a smooth surface, and thus a thickness variation can be suppressed and the Cu layer can be formed with a substantially uniform thickness. In the coil component, a point where the shield layer is thin or a point lacking the shield layer is unlikely to be generated and a functional degradation of the shield layer is effectively suppressed.

Abstract: There is no consideration on performing charging control on a battery necessary for limp-home travel according to a travel environment of a vehicle. It is assumed that the vehicle changes a travel lane to a second travel lane by overtaking or the like between time t1 and t0. The second power generation threshold generation unit 33 refers to the lookup table 50 illustrated in FIG. 5 and reads 70 as the second charging threshold SOCth2. Then, the second charging threshold SOCth2 is larger than the first charging threshold SOCth1 as illustrated in FIG. 6(C), and thus, the threshold selection unit 34 outputs the second charging threshold SOCth2 as the selected charging threshold SOCth. At this time, the SOC of the battery is lower than the charging threshold SOCth, and thus, the power generation command value GEN is turned on at time t1, and the power generation engine is started to charge the battery.
