## Abstract

A cover glass integrated sensor has an excellent visibility of sharp outlines of the display screen as seen through the cover glass and has a sense of unity in appearance in portions surrounding the display screen. The cover glass integrated sensor includes a cover glass and a capacitance type film sensor. The cover glass includes a glass substrate and a first frame-like light-blocking layer made of a screen printing film formed on peripheral portion on the rear surface of the glass substrate. The capacitance type film sensor has a second frame-like light-blocking layer made of an exposure/development product of color resist material formed on a periphery of the front surface. The capacitance type film sensor is attached to a rear surface of the cover glass. An inner edge of the second frame-like light-blocking layer is closer to the center than an inner edge of the first frame-like light-blocking layer.
