Abstract

A wiring substrate that is provided enables stray capacitance between a first electrode and a second electrode to be prevented from varying when an undulation occurs in the wiring substrate. Insulating layers are stacked. A first electrode and a second electrode are formed between the same layers at an interval. The thickness of the first electrode is more than the thickness of the second electrode. The lower main surface of the first electrode is located at a position lower than the lower main surface of the second electrode, and the upper main surface of the first electrode is located at a position higher than the upper main surface of the second electrode when seen through in a direction perpendicular to a stacking direction of the insulating layers.
