Abstract: A multilayer resin substrate includes a stacked body, and a coil including a first coil conductor pattern and a second coil conductor pattern. The second coil conductor pattern includes a wide portion with a line width larger than a line width of the first coil conductor pattern. The wide portion includes overlapping portions that overlap with the first coil conductor pattern, and non-overlapping portions that do not overlap with the first coil conductor pattern, when viewed in a Z-axis direction. Adjacent non-overlapping portions in the Z-axis direction, when viewed in the Z-axis direction, protrude in opposite directions to each other in a radial direction, with respect to the first coil conductor pattern.

Abstract: A multilayer resin substrate includes a stacked body and a coil including coil conductor patterns. A first coil conductor pattern includes a first non-overlapping portion not overlapping with a second coil conductor pattern, when viewed in a Z-axis direction. A second coil conductor pattern includes a second non-overlapping portion not overlapping with the first coil conductor pattern, when viewed in the Z-axis direction. The first non-overlapping portion protrudes more to an outer peripheral side in a radial direction than the second coil conductor pattern, and the second non-overlapping portion protrudes to an inner peripheral side in the radial direction.
