The present invention relates to a collective friction plate in a pantograph of an electric rail car and a manufacturing method thereof. The collective friction plate according to the present invention includes an additive of 0.1-6 wt% formed with one or more selected from: 80-92 wt% of Cu, 3-8 wt% of Sn, 1-6 wt% of graphite and Fe; a ferro alloy formed with one or more selected from Fe-Mo, Fe-Ti and Fe-Cr; and Cr, wherein the particle size of the additive is less than or equal to 250 um, and the particle size less than or equal to 45 um in the additive accounts for 30-50 wt% of an entire additive. The manufacturing method according to the present invention comprises: a step of preparing raw material mixed powder which includes additive powder of 0.1-6 wt% formed with one or more selected from: 80-92 wt% of Cu, 3-8 wt% of Sn, 1-6 wt% of graphite and Fe; a ferro alloy formed with one or more selected from Fe-Mo, Fe-Ti and Fe-Cr; and Cr; a step of sintering the mixed power at the temperature of 650-900C after performing pressure-molding on the mixed power; and a step of impregnating machine oil in the sintered body manufactured from the above. The particle size of the additive is less than or equal to 250 um, and the particle size less than or equal to 45 um in the additive accounts for 30-50 wt% of an entire additive. Thereby, the collective friction plate according to the present invention can have excellent heat resistance, abrasion resistance, lubricity and rainfastness.
