<p><P>PROBLEM TO BE SOLVED: To provide a transparent piezoelectric sensor superior in durability and a transparent input device having the plurality of sensors as key pads. <P>SOLUTION: In the transparent piezoelectric sensor, a transparent pressure sensing layer 1 having the piezoelectricity and a pair of transparent conductive film layers 2 and 2' disposed opposite each other through the transparent pressure sensing layer 1 are formed between a pair of transparent substrates 3 and 3' disposed opposite each other. The transparent input device includes the plurality of transparent piezoelectric sensors, as a single key. Because the transparent conductive film layers 2 and 2' are not required so as to be deformed, unlike the conventional, the transparent piezoelectric sensor and the transparent input device superior in the durability can be provided. Because the transparent conductive film layers 2 and 2' are not brought into contact with each other even when an external pressure is applied, the flaw due to the contact can be also prevented. When a transparent conductive film layer 2'' is formed, an external unnecessary noise is securely prevented from being mixed. <P>COPYRIGHT: (C)2004,JPO</p> |
