Abstract

Provided is a bonding capillary that includes a body including an insertion hole in which a wire is inserted, a first pressing face that presses the wire and that includes a first sloping face provided around the insertion hole and inclined with respect to a direction in which the insertion hole extends, and a second pressing face that presses the wire and that includes a tapered face and a second sloping face, the tapered face being provided between the first sloping face and the insertion hole and having a tapered shape, the second sloping face being provided between the tapered face and the first sloping face, wherein a root-mean-square gradient of a roughness curve element on the second sloping face is smaller than a root-mean-square gradient of a roughness curve element of the first sloping face.
