Abstract: A high-pressure pump includes a valve member that allows or blocks a flow of fuel to a pressure chamber. A needle is reciprocable inside a cylinder member. One end of the needle facing the pressure chamber is provided with the valve member. Another end of the needle is provided with a movable core that faces a fixed core in an axial direction of the needle. The high-pressure pump includes a coil assembly that includes a coil, a terminal connected to the coil, and first and second yokes that form a magnetic circuit on both sides of the coil in the axial direction. The coil assembly is between a first connection portion and a second connection portion. The first connection portion connects the coil assembly and the fixed core. The second connection portion connects the coil assembly and the cylinder member.
