Abstract
Provided is a circuit board in which visibility of an alignment mark is improved. In a case of manufacturing a substrate module in which a touch panel () and an FPC () are electrically connected, an alignment mark in the FPC () is formed by an opaque metal film, so that visibility is high. Consequently, when an alignment mark () in the touch panel () is also formed by an opaque metal film, the visibility of the alignment mark () also becomes high. By performing alignment using the alignment marks having high visibility, alignment between the touch panel () and the FPC () can be performed easily with high precision. As a result, the yield of the substrate module increases and modification of an alignment apparatus used for alignment becomes unnecessary, so that the manufacturing cost of the substrate module can be decreased.
