PURPOSE: A method for bonding wire is provided to reduce a height difference between a first and a second bonding points and to maintain a safe wire loop shape strongly by raising a capillary upwards or askew upwards. CONSTITUTION: A wire(3) penetrating a capillary(4) is connected between a first bond point(A) and a second bonding point(G). A ball is formed with a front end of the wire(3) extended from a front end of the capillary(4), and the capillary(4) is raised while unwinding the wire(3) from the front end of the capillary(4). The capillary(4) is lowered up to a position over the second bonding point(G) approached to the side of the first bonding point(A) rather than the side of the second bonding point(G). When the capillary(4) is raised askew, a raising direction of the capillary(4) is along with a camper surface. |
