Summary:PROBLEM TO BE SOLVED: To provide a load drive device that reduces conduction noise.SOLUTION: According to a table 50 of lamp load drive patterns, at the first timing t1, a microcomputer 11 outputs a PWM control signal to a switching control circuit 14 for driving a right headlight (H) 41. At the next timing t2, the microcomputer 11 outputs a PWM control signal to a switching control circuit 15 for driving a left headlight (H) 42. At a further timing t5, the microcomputer 11 simultaneously outputs PWM control signals to a switching control circuit 18 for driving a right fog lamp 45 and a switching control circuit 20 for driving a right position lamp 47. At a subsequent timing t6, the microcomputer 11 simultaneously outputs PWM control signals to a switching control circuit 19 for driving a left fog lamp 46 and a switching control circuit 21 for driving a left position lamp 48.
