Abstract
A glass film laminate () for a touch panel includes a glass film (), a glass film (), a glass film (), and transparent adhesive layers (). The glass films (), () form both outermost layers. The glass film () has a transparent conductive layer () formed on each of both surfaces thereof. The glass films (), (), () each have a thickness of 200 μm or less. The glass film laminate () for a touch panel itself assumes a curved state without the application of an external force, in which a curved concave surface () and a curved convex surface () are formed. The curved concave surface () has formed therein a compressive stress, and the curved convex surface () has formed therein a tensile stress.
