Wiring board with filter circuit and electronic device

A wiring board with a filter circuit comprising:

• an insulating base that has flexibility;
• a conductor pattern provided on the insulating base;
• and
• a filter circuit defined by the conductor pattern;
• wherein
• the insulating base includes an intermediate member, and a first end member, a second end member, and a third end member that are connected to the intermediate member;
• the first end member and the second end member are disposed along a signal transmission direction with the intermediate member being provided between the first end member and the second end member;
• a first external connection terminal is provided on the first end member, the first external connection terminal being disposed on a first end of the conductor pattern of the filter circuit in the signal transmission direction;
• a second external connection terminal is provided on the second end member, the second external connection terminal being disposed on a second end of the conductor pattern in the signal transmission direction;
• a first ground connection terminal that grounds the filter circuit is provided on the intermediate member;
• and
• a second ground connection terminal that grounds the filter circuit is provided on the third end member.
