A pump device includes a first case, a second case, a sacrificial anode. The first case has a channel in which hydraulic fluid flows. The second case provides in contact with the first case. The sacrificial anode is coupled to one of the first case and the second case and suppresses corrosion of the first case and the second case. At least one of the first case and the second case includes an insulating section that interrupts electric coupling between the first case and the second case. The pump device further includes a valve member provided in the channel, controlling the flow of the hydraulic fluid flowing in the channel, and electrically coupling the first case and the second case.
