PURPOSE:The titled adhesive for carrying out minute electrical connection, obtained by coating the surface of transparent powder or granule with a trans parent electrically-conductive material to give a transparent electrically- conductive powder or granule and dispersing the powder or granule into a transparent resin solution consisting of a polymer binder and a solvent. CONSTITUTION:The surface of transparent powder or granule (e.g., glass, mica, etc.) is coated with a transparent electrically-conductive substance capable of forming a transparent electically-conductive film of an oxide such as indium oxide, tin oxide, etc. The powder or gradule is dispersed into a transparent resin solution consisting of a polymer binder which has photo-setting or photo- decomposition to produce solubility difference, to give the aimed adhsesive. The adhesive is applied to an electrode connecting terminal group formed on an insulating substrate, dried and piled on another connecting terminal group by heat contact bonding. Then the surface or back of the insulating substrate is exposed to light, developed and unnecessary transparent electrically-conductive adhesive between the neighboring terminals is removed to finish connection.
