Abstract
As a substrate having a fine line and capable of suppressing crack generation in the substrate and peeling of the fine line, the invention discloses a configuration in which plural recesses are arranged on the fine line, and particularly a configuration in which the interval of the plural recesses does not exceed 200 μm. There is also disclosed a configuration in which the plural recesses are arranged along a direction crossing the longitudinal direction of the fine line.
