A first pattern (10) and a second pattern (20) are laminated, a GND (103) is formed as a beta pattern of a pattern of a first high voltage circuit (100), a GND (253) is formed as a beta pattern of a pattern of a second low voltage circuit (250), and the anti-noise performance of a high voltage circuit is improved as a result of the beta pattern of the GND (103) of the pattern of the first high voltage circuit (100) and the beta pattern of the GND (253) of the pattern of the second low voltage circuit (250) having one portion facing each other. |
