To suppress the increase in the reduction of workability and the increase of electric resistance in a sheet-shaped contact material for a fuse by the reduced quantity of oxide or the like to be added.

The sheet-shaped contact material is obtained by subjecting an Ag alloy having a composition composed of Ag, and additional metals with inevitable impurities to internal oxidation, and, as the additional metals, by weight, 3 to 10% Sn and 0.5 to 10% In are comprised. In this way, Sn formes a fine oxide (such as SnO2) dispersed phase thermally stable and fine by the internal oxidation treatment, so as to improve its adhesion resistance. Further, In promotes the oxidation of Sn in the internal oxidation treatment, and In itself forms a stable oxide (such as In2O3) dispersed phase, so as to improved its adhesion resistance.
