<p>PURPOSE:To improve resiliency and strength, enable light operation input, and elongate key strike durability life by forming dot spacers between transparent conductors facing each other mainly of resin composition including epoxy compound of a rigidity of a specific value or less. CONSTITUTION:Amine or polyamine is added as hardening agent or hardening catalyst to urethan or polyether-denaturated epoxy resin or the like as epoxy compound. After resin compound such as polybutadiene or polychloroprene is added to this for adjusting rigidity, silica or alumina as filler, plasticizer, solvent levelling agent, etc., are blended with it. Dot spacers 5 formed of paste of this are mounted on a glass on which transparent conductors 3, 4 are formed, or on one of lower boards 2, 3 to be dried or reaction-hardened. The spacer 5 is thus provided with a rigidity of JIS-A95 or less, it has sufficient resiliency, and its strength is improved. Light operation input is thus achieved, and key strike durability life is elongated.</p> |
