A capacitor array includes a plural capacitors provided separated at intervals from each other. A first wiring line is connected to the first electrode of each of the plurality of capacitors, and is provided so as to pass through the intervals between the plurality of capacitors. A second wiring line is connected to the second electrode of each of the plurality of capacitors, is provided in a layer separated by at least one layer from the layer in which the first wiring line is provided, and is provided so as to pass through the intervals between the plurality of capacitors. A first conductor is provided in a layer between the layer in which the first wiring line is provided and the layer in which the second wiring line is provided, so as to be interposed between the first wiring line and the second wiring line.
