The invention relates to touch panels for use in a variety of electronic apparatuses, and designed to prevent separation of a lower substrate and an antireflection layer, and to ensure reliable operation. An undercoat layer () made of any of silicon oxide and a compound having a principal ingredient of silicon oxide is disposed between the antireflection layer () and the lower substrate () made of glass having the same principal ingredient of silicon oxide, to improve strength of adhesion between the lower substrate () and the antireflection layer (), thereby preventing separation of the antireflection layer () from the lower substrate (), and providing the touch panel with reliable operation.

Touch panel

A seat sensor includes a top sheet made of insulating film; an upper insulating layer with insulating particles partially protruding from the surface of the upper insulating layer; and an upper resistor layer formed over the upper insulating layer. The seat sensor further includes a bottom sheet made of insulating resin film disposed under the top sheet; a lower insulating layer with insulating particles partially protruding from the surface of the lower insulating layer; a lower resistor layer formed over the lower insulating layer, and an insulating spacer layer formed between the top sheet and the bottom sheet. The above construction provides a seat sensor that has stable resistance properties even after repeated loading and a detection device using the seat sensor.
