<p>A wiring board comprises an insulating substrate (2) having one major surface which is provided with a first region (3) and a second region adjoining thereto, a plurality of signal line groups arranged on the first region (3), and a plurality of connecting portions (4) which are so arranged on the second region as to correspond to the respective signal line groups. Each connecting portion (4) contains first to third terminal groups (5c, 5a, 5b), a first wiring group (6c) where the first terminal group (5c) is connected with a corresponding signal line group, a second wiring group (6a) connected to the second terminal group (5a), and a third wiring group (6b) connected to the third terminal group (5b). The second wiring group (6a) of one connecting portion (4) is connected with the third wiring group (6b) of the adjoining connecting portion (4). All the connecting portions (4) are identical with each other in the shapes of the first to third terminal groups (5c, 5a, 5b) and the first to third wiring groups (6c, 6a, 6b).</p> |
