The invention discloses silver conductor paste with strong adhesive force for a 5G ceramic dielectric filter. The silver conductor paste comprises the following components in percentage by weight: 55-70% of spherical silver powder, 6-20% of flake silver powder, 0.5-3% of glass powder, 0.2-2% of a mixture of active dolomite powder and cryolite powder after heat treatment, 8-15% of an organic carrier, 1-5% of a paste modifier and 5-11% of an organic diluent. The dolomite powder and cryolite powder raw materials are subjected to heat treatment to form an active dolomite powder and cryolite powder mixture, the active dolomite powder and cryolite powder mixture is added into the conductive silver paste, the high-adhesive-force silver conductor paste is finally obtained, peeling does not occur at the drawing position, and meanwhile it is tested that weldability is good, and conductivity is excellent. After the silver conductor paste is applied to series 5G ceramic dielectric filter ceramic chips, the leveling property is good, a metallized film layer is flat, the adhesive force is improved, meanwhile, the conductive performance of the paste is considered, the insertion loss of a filter can be effectively reduced, and the filter has a high quality factor.
