PROBLEM TO BE SOLVED: To provide a power supply equipment which can be easily reduced in size by suppressing the interference between power lines and load lines. SOLUTION: Wiring patterns 6a connected by power lines and shorter wiring patterns 7a connected by load lines 7 are formed on opposite faces of a printed wiring board 5. Since these two types of wiring patterns are distributed to the front and the rear face of the double-sided printed wiring board, interference between these wiring patterns can be suppressed, preventing interference between the power lines and the load lines. Due to this structure, the connections between the power lines and the corresponding wiring patterns and those between the load lines and the corresponding wiring patterns can be disposed close to each other, thus facilicating reduction in size of power supply equipment. |
