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.
