PURPOSE: An antibacterial sheet material for manufacturing radiating pin of heat exchanger is provided which is suitable for preventing generation of malodor during operation of an air conditioner by suppressing parasitism of bacteria on a hydrophilic thin film deposited on the radiating pin, and a manufacturing method thereof is provided. CONSTITUTION: The antibacterial sheet material for manufacturing radiating pin of heat exchanger comprises a polymer layer(12) that is deposited on the surface of a metal sheet material(11) to increase hydrophilicity; a copper film(13) that is deposited on the surface of the polymer layer to restrain propagation of bacteria; and an activation layer(14) that is deposited on the surface of the copper film to increase the initial hydrophilicity, wherein the copper film is deposited on the surface of the polymer layer by sputtering in a deposition chamber equipped with a copper electrode. The manufacturing method of the antibacterial sheet material for manufacturing radiating pin of heat exchanger comprises the steps of depositing a polymer layer on the surface of a metallic material by plasma treatment; forming a copper film for restraining propagation of bacteria on the surface of the polymer layer by plasma treating the polymer layer deposited material; and forming an activation layer for increasing the initial hydrophilicity on the surface of the copper film by plasma treating the copper film formed material.
