Abstract
The second wiring pattern includes extended regions from the main body side to the projecting portions as seen in a direction in which the pair of leads extend, and wiring regions continuously spreading from the extended regions in a direction away from the main body. Supposing that a length of the wiring region from an end of the projecting portion as a reference point to a farthest position in a direction away from the main body is a first width and a width of the extended region in a direction parallel to a side opposed to the main body side through the end of the projecting portion is a second width, the first width is smaller than the second width. The second insulating substrate is sandwiched between the second wiring pattern and a base, and thereby, a capacitance is formed.
