摘要： A coating process includes adding a body to a reactor; adding a metal alkoxide or precursors thereof to the reactor; adding a catalyst for the hydrolysis of the metal alkoxide to the reactor; and coating the surface of the body with a metal oxide-containing coating layer through the hydrolysis and dehydration condensation of the metal alkoxide. The addition of a body precedes at least one of the addition of a metal alkoxide or precursors thereof and the addition of a catalyst.

摘要： An insulating layer, which is composed of a material having a higher insulating property than a core, partially covers a surface of the core. A plating layer, which functions as an electrode, is stacked on a surface of the insulating layer. The surface area of the insulating layer is larger than the surface area of the plating layer and the plating layer is stacked inside a region covered by the insulating layer.

摘要： A negative-temperature-coefficient thermistor component includes a core. Surfaces of the core are partially covered with a first insulating layer. Surfaces of the core are partially covered with a second insulating layer. The first insulating layer and the second insulating layer overlap each other on a first side surface and a second side surface, each of which is one of the surfaces of the core.
