Multilayer resin substrate and method of manufacturing multilayer resin substrate

A multilayer resin substrate comprising:

• a stacked body including a plurality of resin layers stacked on each other;
• and
• a coil including a plurality of coil conductor patterns on two or more resin layers, respectively, among the plurality of resin layers, and including a winding axis in a stacking direction of the plurality of resin layers;
• wherein
• the plurality of coil conductor patterns include a first coil conductor pattern and a second coil conductor pattern alternately disposed in the stacking direction;
• the first coil conductor pattern includes:
• a first overlapping portion overlapping with an adjacent second coil conductor pattern, when viewed in the stacking direction;
• and
• a first non-overlapping portion not overlapping with the adjacent second coil conductor pattern;
• the second coil conductor pattern includes:
• a second overlapping portion overlapping with an adjacent first coil conductor pattern, when viewed in the stacking direction;
• and
• a second non-overlapping portion not overlapping with the adjacent first coil conductor pattern;
• the first non-overlapping portion protrudes more to an outer peripheral side in a radial direction of the plurality of coil conductor patterns than the adjacent second coil conductor pattern;
• the second non-overlapping portion protrudes more to an inner peripheral side in the radial direction than the adjacent first coil conductor pattern;
• the first coil conductor pattern and the second coil conductor pattern are alternately disposed in the stacking direction on three or more resin layers, respectively, among the plurality of resin layers;
• the first coil conductor pattern does not protrude to the inner peripheral side from any portion of the first coil conductor pattern overlapping with the adjacent second coil conductor pattern, when viewed in the stacking direction;
• the second coil conductor pattern does not protrude to the outer peripheral side from any portion of the second coil conductor pattern overlapping with the adjacent first coil conductor pattern, when viewed in the stacking direction;
• a width of the first non-overlapping portion in the radial direction is less than a width of the first overlapping portion in the radial direction;
• and
• a width of the second non-overlapping portion in the radial direction is less than a width of the second overlapping portion in the radial direction.
