ABSTRACT:
A thin film circuit substrate is provided with a voice-output-section driving section, formed of a thin film layer on an insulative substrate, for driving a voice output section. An antisurge section, provided on a wiring between the voice-output-section driving section and an output terminal section thereof, includes an antisurge element. When a surge voltage is applied to the wiring, the antisurge element, monolithically formed on the thin film circuit substrate, connects the wiring to the ground so as to pass a current (surge current), generated by the surge voltage applied to the wiring, to the ground. This makes it possible to provide a thin film circuit substrate which is monolithically provided with a function which can protect a circuit section when a voltage exceeding a predetermined range is applied to the wiring linking the circuit section with an input terminal section or an output terminal section.
