The second conductors are spaced apart from the first conductor in a second direction crossing a first direction and are mutually juxtaposed with spacing in the first direction. The heat-generating elements are mutually juxtaposed in the first direction and connected to the respective second conductors and the first conductor. The first protruding conductor protrudes from either of the first conductor and one of the second conductors and is connected to a first one of the heat-generating elements. The first protruding conductor is at least partly located, in the first direction, between a center of the first one of the heat-Generating elements and a center of a second one of the heat-generating elements adjacent to the first one. ## Claims ### Claim 1 A wiring structure comprising: a substrate; a first conductor that extends in a first direction; a plurality of second conductors that is spaced apart from the first conductor in a second direction and mutually juxtaposed with spacing in the first direction, the second direction being along one face of the substrate and crossing the first direction; a first trace on the face of the substrate, connected to the first conductor; a plurality of second traces that is apart from the first trace on the face, and connected to the second conductors, respectively; a plurality of heat-generating elements that generates heat by an applied voltage, the heat-generating elements that are spaced apart from the second traces and mutually juxtaposed with spacing in the first direction, and connected to the first conductor and to the second conductors, respectively; and a first protruding conductor that protrudes from either the first conductor and one of the second conductors to a location between the first conductor and the second conductors in the second direction, and is connected to a first one of the heat-generating elements, wherein the first protruding conductor is at least partly located between a center of the first one of the heat-generating elements and a center of a second one of the heat-generating elements in the first direction, the second one of the heat-generating elements being adjacent to the first one of the heat-generating elements. ### Claim 2 (depends on 1) The wiring structure according to claim 1, wherein the first protruding conductor has a length in the second direction shorter than a half of a length of the connected, first one of the heat-generating elements in the first direction. ### Claim 3 (depends on 1) The wiring structure according to claim 1, wherein the first protruding conductor has, in the second direction, a length which elongates toward a gap between the first one of the heat-generating elements and the second one of the heat-generating elements. ### Claim 4 (depends on 1) The wiring structure according to claim 1, wherein in the first direction, the first protruding conductor is shorter in length than the connected, first one of the heat-generating elements. ### Claim 5 (depends on 1) The wiring structure according to claim 1, further comprising a second protruding conductor that: protrudes from the other of the first conductor and one of the second conductors to a location between the first conductor and the second conductors in the second direction, is connected to the first one of the heat-generating elements connected to the first protruding conductor, and is juxtaposed to the first protruding conductor with a gap in the second direction. ### Claim 6 (depends on 1) The wiring structure according to claim 1, wherein the first protruding conductor comprises a plurality of first protruding conductors, the first protruding conductors that: protrude from either of the first conductor and one of the second conductors to a location between the first conductor and the second conductors in the second direction, and are connected to the heat-generating elements, respectively, and two of the first protruding conductors are adjacent each other with a gap between the first one of the heat-generating elements and the second one of the heat-generating elements. ### Claim 7 (depends on 1) A fuser device comprising: the wiring structure according to claim 1; and a roller that applies pressure to a medium on which a toner image is formed, while the medium is heated by at least one of the heat-generating elements. ### Claim 8 (depends on 7) An image forming apparatus comprising: the fuser device according to claim 7.
