<P>PROBLEM TO BE SOLVED: To provide a sheet-like switch member which is excellent in operability such as clicking nature and has high moldability. <P>SOLUTION: The sheet-like switch member used for an input section of an equipment is structured of a laminated sheet including a hard layer formed of resin components, and a soft layer laminated at least on one surface of the hard layer and made from chain olefin-cyclic olefin copolymers. The hard layer may be made of a stretched film (especially, stretched polyester film). The hard layer and the soft layer may be laminated through an adhesive layer in the sheet-like switch member. The soft layer may be formed on one surface of the hard layer in the sheet-like switch member, and a protection layer capable of peeling off may be further formed on the soft layer. Crystallinity of the chain olefin-cyclic olefin copolymer may be 20% or less. The sheet-like switch member can be used for a key top sheet, a light guide sheet, or a reflecting sheet in order to constitute a push-button switch, a membrane switch, a sensor switch, or a touch panel. <P>COPYRIGHT: (C)2011,JPO&INPIT |
