On the electronic substrate of the connection structure, at a location where a connector is to be mounted, a Type 1 connector line is marked in an X1 direction, and a Type 2 connector line is marked in an X2 direction. A Type 1 cable line is marked so as to be partly exposed with respect to the flat cable, and a Type 2 cable line is adjacently marked on the outer side thereof. At the edge in the X2 direction, the Type 2 cable line is covered, and the Type 1 cable line is adjacently marked on the outer side thereof. The Type 1 lines are solid lines and the Type 2 lines are dashed lines. ## Claims ### Claim 1 A connection structure having a connector, a flat cable, and an electronic substrate, wherein the connector is configured to connect to the flat cable and to mount on the electronic substrate, comprising: a Type 1 connector line, on the substrate, extends along a length direction of the flat cable on one side of the substrate in a width direction that is orthogonal to the length direction; and a Type 2 connector line, on the substrate, extends along the length direction on an opposite side of the substrate, both of the Type 1 and Type 2 connector lines being at a location where the connector is to be mounted on the substrate; and a Type 1 cable line and an adjacent Type 2 cable line, both on the substrate, extend along the length direction on both ends of the substrate in the width direction at a location where the flat cable extends when connected to the connector, wherein the Type 1 connector line and the Type 2 connector line are configured to be covered by the connector when mounted in alignment on the substrate, with outer edges of the Type 1 and Type 2 connector lines matching outer edges of the connector, at an edge of one side of the flat cable, a Type 1 cable line extends along on an inner side thereof and a Type 2 cable line extends along on an outer side thereof, with the edge of the one side being a border between the Type 1 and Type 2 cable lines on the one side, at an edge of another side of the flat cable, a Type 1 cable line extends along on an outer side thereof and a Type 2 cable line extends along on an inner side thereof, with the edge of the another side being a border between the Type 1 and Type 2 cable lines on the another side, the Type 1 connector line and the Type 1 cable line are lines of the same type, and the Type 2 connector line and the Type 2 cable line are lines of the same type but are lines of a different type from the Type 1 connector line and the Type 1 cable line. ### Claim 2 A connection structure having a connector, a flat cable, and an electronic substrate, wherein the connector is configured to connect to the flat cable and to mount on the electronic substrate, comprising: a Type 1 connector line, on the substrate, extends along a length direction of the flat cable on one side of the substrate in a width direction that is orthogonal to the length direction;
