A high-pressure pump (1) is equipped with a plunger (13) that moves in a reciprocating manner, a pressurization chamber (121) in which fuel is pressurized by the plunger (13), a fuel chamber (16) that accommodates a pulsation damper (50) and through which fuel flows, and a housing (11) that houses the fuel chamber. The fuel chamber (16) is connected to a return passage (310) through which fuel is returned from the fuel chamber (16) to a fuel tank (301) In addition, a connection passage (68) that includes a throttle (69) connects the fuel chamber (16) to the return passage (310).
