A high pressure fuel pump (20) that pressurizes and supplies a fuel by driving a cam (21) such that a plunger (23) reciprocates, the high pressure fuel pump (20) comprises a lifter guide (25) having a guide hole (25A), a lifter (22) that is disposed between the cam (21) and the plunger (23) and is fitted into the guide hole (25A) to be free to slide so as to transmit a driving force from the cam (21) to the plunger (23), an oil collection portion (27) that is provided above the guide hole (25A) so as to surround a periphery of the lifter (22), and stores a lubricating oil for lubricating a sliding portion between the lifter (22) and the guide hole (25A), and an oil supply passage (25C) for supplying the lubricating oil to the oil collection portion (27). As a result, a reduction in a lubricating performance with regard to the lifter (22) in a position away from an opening portion of the oil supply passage (25C) is suppressed.
