The present invention provides a conductive adhesive agent capable of being diluted with a solvent to give good coating workability and allowing formation of a conductive joint excellent in both thermal conductivity and electrical conductivity by inhibiting a gas generated when a binder resin is heat-cured after attachment of a part. The conductive adhesive agent according to the present invention is a conductive adhesive agent wherein, based on 100 parts by weight of silver powder having an average particle diameter of micrometers, which is used for a conductive medium, e.g. as a main component, 1 to 10 parts by weight of silver fine particles having an average particle diameter of nanometers is used in combination therewith and 5 to 15 parts by weight of thermosetting resin as a binder resin component and 10 parts or less by weight of solvent for adjustment of a fluid viscosity are blended therein as essential components, and by selection of such a blending ratio, generation of a gas component during heating and curing of the thermosetting resin to prevent formation of voids, and at the same time, fabrication of a conductive joint excellent in thermal conductivity and electrical conductivity is achieved.

Conductive adhesive agent with ultrafine particles

To provide a method for producing a sensing film for gas sensors by sintering particles comprising a metal or a metal oxide on a substrate, where the sensing film for gas sensors having excellent sensor properties such as sensitivity and responsibility can be easily and simply formed. A nano-meter order particle (), a dispersant () for preventing aggregation of the particles (), and a scavenger () for trapping the dispersant () at the sintering are mixed in a solvent () to prepare a paste body (), and this paste body () is coated on a base material and fired, thereby forming a sensing film.
