Abstract: Disclosed is a semiconductor device in which, when two adjacent semiconductor chips are coupled with bonding wires, a short circuit between the adjacent bonding wires can be suppressed. A first bonding wire, a second bonding wire, a third bonding wire, and a fourth bonding wire are lined up in this order along a first side. When viewed from a direction perpendicular to a chip mounting part, a maximum of the space between the first bonding wire and the second bonding wire is larger than that of the space between the second bonding wire and the third bonding wire. Further, a maximum of the space between the second bonding wire and the third bonding wire is larger than that of the space between the third bonding wire and the fourth bonding wire.
