PURPOSE: A rolled sheet for a connector terminal and a manufacturing method thereof are provided to reduce the product unit cost of a connector by increasing the number of pins per connector. CONSTITUTION: A manufacturing method of a rolled sheet for a connector terminal comprises the steps for manufacturing a rolled sheet(10) in the bas layer, forming by laminating a nickel strike plating layer, a copper-electroplated layer or a tin coating layer at least one or two tin coating layer, forming a pattern hole(11) by executing the micro patterning rolling by using a rolling roll(13). The Cu-SN compound powder(15) is supplied to the surface of the rolled sheet. The surplus powder is eliminated through a screen(17) after filling in the pattern hole. The rolled sheet in which the surplus powder is removed is reflow-heated. The Cu-SN compound powder is melted as the Cu-SN metallic compound(18).
