Abstract
A touch panel comprises a pair of glass substrates ( ) each having a transparent conducting, film ( ) formed on its one side surface. The glass substrates disposed with their respective transparent conducting films ( ) is faced each other and bonded together around their peripheries by a seal ( )having spacers ( ′) of insulating material incorporated therein, in which lead-out patterns ( ) intersect the seal ( ) prior to extending out of the touch panel. The sphere diameter of the spacers ( ′) is selected to be approximately equal to the particle size of silver particles ( ) contained in the conducting paste, whereby the spacers may dig in between the conducting material particles to thereby reduce the difference in height between the bumps and dips on those portions of the seal intersecting the lead-out patterns and the remaining portions, respectively.
