Abstract: PURPOSE: To obtain a suppression circuit which suppresses a fast transient noise by a method wherein a filter which delays the rise time is provided and a surge absorption element whose surge resistant amount is large and whose response time is slow is provided. CONSTITUTION: In a surge noise which is generated in a DC power supply 400, a part whose rise time is slow is absorbed by a surge absorption element 5.
