Claim 0:
1. A wire bonding method for bonding a first end of a wire to a first bonding surface and bonding a second end of the wire to a second bonding surface, comprising:
bonding the first end of the wire fed from a distal end of a capillary to the first bonding surface;
moving the capillary in a Z direction while feeding the wire from the distal end of the capillary;
moving the capillary in a direction including at least one of an X direction and a Y direction while feeding the wire from the distal end of the capillary;
moving the capillary in a direction including at least one of the X direction, the Y direction, and the Z direction a plurality of times while feeding the wire from the distal end of the capillary;
moving the capillary to a highest position; and
moving the capillary to the second bonding surface and bonding the second end of the wire to the second bonding surface, wherein
the wire bonding method includes, at any timing between the moving of the capillary in the Z direction and the moving of the capillary in the direction including the at least one of the X direction, the Y direction, and the Z direction, rotating the first bonding surface about a rotation axis to move the second bonding surface to a position capable of bonding,
the moving of the capillary to the highest position is performed after the rotating of the first bonding surface, and
an angle formed by the first bonding surface and the second bonding surface on a side where the wire is stretched is 200° or more.
