Abstract: There is provided a passive electronic component that achieves proper recognition of a marker portion thereof that indicates a winding start position and a winding direction of a coil conductor as well as a posture and an orientation of the component. The passive electronic component is a laminated type electronic component and has an insulator portion, a terminal electrode electrically connected to a conductor portion provided inside the insulator portion and formed on a surface of the insulator portion, and a marker portion for indicating a winding start position and a winding direction of a conductor or a posture and an orientation of the component. The marker portion is disposed in a recessed portion on the surface of the insulator portion.

Abstract: A coil component according to one or more embodiments of the invention includes a base body containing a plurality of metal magnetic particles, a coil conductor, and an external electrode. In one or more embodiments, the coil conductor has a coil portion disposed inside the base body, and an end surface exposed from a first surface of the base body. The coil conductor is configured such that the ratio of the dimension of a section of the coil portion in a short axis direction to the dimension of the end surface in a short axis direction is 0.5 to 0.95, the section of the coil portion is orthogonal to the direction in which current flows through the coil portion. In one or more embodiments, the external electrode is provided on the first surface such that it is connected to the end surface of the lead-out portion.
