A terminal manufacturing apparatus includes a pressing device adapted to form a chained terminal including a crimp portion by bending a continuously supplied plate-shaped workpiece into a hollow shape, the crimp portion being crimpable with a conductor part of a coated conductor accommodated therein, a welding device adapted to bring two edge portions of the crimp portion in proximity to each other and join the two edge portions by welding, a conveying/positioning time calculating unit adapted to determine a conveying/positioning time of the welding device on the basis of a machining time required by the pressing device and the welding device, and a conveying/positioning mechanism adapted to position the chained terminal in a welding machining position within the welding device in accordance with the conveying/positioning time.
