Abstract: Connection patterns of plural diodes include a first series connection pattern and a second series connection pattern. The first series connection pattern extends from an input terminal in the X direction. The second series connection pattern has a portion through which a current flows to approach the input terminal. The first series connection pattern includes a first diode, which is the first diode counted from the input terminal. The second series connection pattern includes a second diode, which is the last diode counted from the input terminal. The second diode is disposed separately from the first diode with some distance therebetween in the Y direction. An N-type region of the first diode and a P-type region of the second diode directly oppose each other as viewed in a planar direction.
