Claim Text:
1. A manufacturing method of a semiconductor device comprising: passing out wire to stretch in a first direction from a first bond formed on a first electrode and then folding back the wire in a second direction different from the first direction; pressing down the folded-back wire against the first bond to form a folded-back portion in a shape in which it is squashed; bonding the wire passed out to stretch from the folded-back portion, to a connection of a substrate so as to form a first loop linking the connection and the first bond; and bonding wire passed out to stretch from a second bond formed on a second electrode, to the folded-back portion so as to form a second loop linking the first bond and the second bond, wherein in forming the second loop, an end of the wire is bonded to the first loop at a second position offset in a direction in which the first loop extends, from a first position that is the center of the first bond.
