A noise reduction type fuel pressure control device is provided to maintain pressure of inside regularly and to suppress water velocity noise of fuel. A noise reduction type fuel pressure control device comprises a housing(110) in which the electromagnet(111) is formed, a path(120) in the fuel rail(1) and high pressure pump return line(2), a needle valve(130) extended to the flow path part inside, and a fuel damper(140) which prevents that the fuel of the flow path part inside is tottery by the pressure gradient.
