Abstract: Disclosed herein is a noise suppression sheet that includes a substrate having a first through hole, and a conductor pattern provided on one surface of the substrate. The conductor pattern has a plurality of linear patterns extending in a first direction and a connection pattern connecting the plurality of linear patterns. The one surface of the substrate has a clearance area surrounded by the plurality of linear patterns and having no conductor pattern. The size of the clearance area in a second direction different from the first direction is larger than an arrangement pitch between the plurality of linear patterns in the second direction. The first through hole is formed in the clearance area.

Abstract: Disclosed herein is a coil module that includes a holder having a flat-plate part for placing thereon a target device, a first stopper extending in a first direction along a first side of the flat-plate part, and a second stopper extending in a second direction orthogonal to the first direction along a second side of the flat-plate part; and a coil provided so as to overlap the flat-plate part of the holder. As viewed in a coil axis direction, an outer size of the coil in a third direction inclined at a predetermined angle with respect to the first direction is larger than an outer size of the coil in a fourth direction orthogonal to the third direction.

Abstract: Disclosed herein is a coil component that includes a coil pattern provided on the substrate. The outer and inner shapes of the coil pattern are both larger in width in a first direction than a second direction. The outer shape of the coil pattern has a pair of first outer shape sections and a second outer shape section positioned between the pair of first outer shape sections in the first direction and having a width in the second direction larger than that of the first outer shape sections. The inner shape of the coil pattern has a pair of first inner shape sections and a second inner shape section positioned between the pair of first inner shape sections in the first direction and having a width in the second direction larger than that of the first inner shape sections.

Abstract: Disclosed herein is a coil component that includes a substrate having a first surface, and first and second coil patterns coaxially formed on the first surface of the substrate and electrically isolated from each other. The first coil pattern has a plurality of turns including a first turn and a second turn. A predetermined turn of the second coil pattern is disposed between the first and second turns of the first coil pattern.
