Abstract
Provide is a high-pressure fuel pump capable of improving the degree of freedom of layout of members to be attached to a pump body and a producing method thereof. Therefore, the high-pressure fuel pump includes the suction joint that sucks fuel, the pump body formed with the pressurizing chamber that pressurizes the fuel sucked from the suction joint, and the discharge joint that discharges the fuel pressurized in the pressurizing chamber. The pump body is formed so that at least a part of the side surface portion thereof becomes a cylindrical portion or a polygonal shape portion. At least one of the discharge joint and the suction joint may be fixed on the inner peripheral side with respect to the outermost peripheral portion of the cylindrical portion or the polygonal shape portion of the side surface portion.
