Abstract
A high-pressure pump includes a pressurizing chamber forming portion including a cylindrical inner peripheral wall that defines a pressurizing chamber, a plunger, a housing including a housing outer peripheral wall, a valve member, an electromagnetic driving unit, a discharge passage portion, and a fixed portion that is connected to the housing. The fixed portion has multiple bolt holes. The multiple bolt holes are arranged radially outward of the housing outer peripheral wall in a circumferential direction when viewed along a direction of an axis of the cylindrical inner peripheral wall. The high-pressure pump is virtually divided into a first region and a second region by a virtual surface on which axes of adjacent ones of the multiple bolt holes and an axis of the cylindrical inner peripheral wall extend. Both the electromagnetic driving unit and the discharge passage portion are located in the first region or the second region.
