Abstract
A wiring substrate includes an insulating base that has a plate surface; a first circuit that is provided on the plate surface; a first terminal that is provided on the plate surface, and to which a mounting member is attached; a second terminal that is provided on the plate surface; a first wiring that connects the first circuit and the first terminal to each other; and a second wiring that connects the first terminal and the second terminal to each other, is electrically connected to the first wiring in the first terminal, and has a parallel section in which the second wiring is disposed close to and parallel to the first wiring without being electrically connected to the first wiring outside the first terminal.
Claims24
A wiring substrate comprising:
- an insulating base that has a plate surface;
- a first circuit that is provided on the plate surface;
- a first terminal that is provided on the plate surface, and to which a mounting member is attached;
- a second terminal that is provided on the plate surface;
- a first wiring that electrically connects the first circuit with the first terminal;
- and
- a second wiring that electrically connects the second terminal and the first terminal and the first wiring, the second wiring having a parallel section in which a portion of the second wiring outside the first terminal is disposed adjacent to and parallel to the first wiring;
- wherein, in the parallel section, the first wiring and the second wiring are formed of conductive films formed in different layers on the plate surface via an insulating film;
- and
- wherein, in the parallel section, the first wiring and the second wiring are at least partially overlapped with each other when viewed from a normal direction of the plate surface.
A wiring substrate comprising:
- an insulating base that has a plate surface;
- a first circuit that is provided on the plate surface;
- a first terminal that is provided on the plate surface, and to which a mounting member is attached;
- a second terminal that is provided on the plate surface;
- a first wiring that electrically connects the first circuit with the first terminal;
- and
- a second wiring that electrically connects the second terminal and the first terminal and the first wiring;
- wherein, the second wiring includes one end electrically connected to the second terminal and the other end electrically connected to the first terminal, the other end is located closer to the first terminal than the first circuit,
- wherein, a part of the second wiring extends along the first wiring, and
- wherein the first wiring and the second wiring are at least partially overlapped with each other when viewed from a normal direction of the plate surface.
