Claim 0:
1. A wiring substrate comprising:
insulating layers that are stacked; and
a first electrode and a second electrode are provided between two layers of the insulating layers, the first electrode being spaced apart from the second electrode,
wherein a thickness of the first electrode is larger than a thickness of the second electrode,
a lower main surface of the first electrode is located at a position lower than a lower main surface of the second electrode, and an upper main surface of the first electrode is located at a position higher than an upper main surface of the second electrode in a stacking direction of the insulating layers when seen through in a direction perpendicular to the stacking direction of the insulating layers,
the first electrode is an inductor or a wiring,
the second electrode is a capacitor or a ground,
an area of the upper main surface of the second electrode is larger than an area of the upper main surface of the first electrode when seen through in a direction parallel to the stacking direction of the insulating layers,
the first electrode has a U-shape comprising three sides and one opening when seen through in the direction parallel to the stacking direction of the insulating layers,
the second electrode has a polygonal shape when seen through in the direction parallel to the stacking direction of the insulating layers, and
the three sides of the first electrode surrounds the second electrode when seen through in the direction parallel to the stacking direction of the insulating layers.
