In a magnetic head measuring apparatus for measuring a magnetic head, an amplitude-modulated electric current whose amplitude is modulated by a specified carrier wave frequency and modulation frequency is applied to a magnetic head. The color filter substrate has a reflection film on the surface of a substrate body. The primary controller provides stimulus, expected, and mask data to the local controllers over the communications path. If the first audio signal is generated, the judgment module generates a first control signal. By providing the opening pattern, the conductive pattern is exposed at the bottom surface of the through-hole.
