Document Type and Number:

Japanese Patent JP2005173551

Kind Code:

A

Abstract:

To provide a photosensitive thick-film paste material for forming a light-transmitting electromagnetic shield, to provide the light-transmitting electromagnetic shield formed by using the material, and a manufacturing method of thereof.

A thick-film black paste and a thick-film conductive paste are applied on a transparent glass substrate or the pastes are stacked in a sheet shape to form a desired geometrical pattern. The thick-film conductive paste comprises a mixture of particles of silver, copper or another metal, an inorganic binder, an organic polymer binder, a photoinitiator and a photosetting monomer. The thick-film black paste comprises a mixture of a black pigment produced from ruthenium oxide, a ruthenium multiple oxide or the like, an inorganic binder, an organic polymer binder, a photoinitiator and a photosetting monomer.
