Abstract:
1. A touch panel comprising: a first transparent substrate; a second transparent substrate facing the first transparent substrate; protrusions formed on a protrusion formation surface, the protrusion formation surface being one of a surface of the first transparent substrate facing the second transparent substrate and a surface of the second transparent substrate facing the first transparent substrate; a first resistive film formed on the protrusion formation surface, the first resistive film covering the protrusions; a second resistive film formed on a protrusion facing surface, the protrusion facing surface being the other of the surface of the first transparent substrate facing the second transparent substrate and the surface of the second transparent substrate facing the first transparent substrate; insulating spacers which regulate a given distance between first contact regions and second contact regions to set a gap between the first contact regions and the second contact regions when the first transparent substrate is not pressed, and to allow the first contact regions and the second contact regions to be in contact with each other when the first transparent substrate is pressed, the first contact regions being parts of the first resistive film and including tops of the protrusions, the second contact regions being parts of the second resistive film and facing the first contact regions; a frame-shaped seal member which circumferentially bonds the first transparent substrate and the second transparent substrate together; and an insulating liquid contained in a space surrounded by the first transparent substrate, the second transparent substrate and the seal member, wherein:
