A valve device includes: a poppet that is formed in a hollow shaft shape except for a leading end, has a tapered closure part at the leading end and a side hole passing through a wall of the hollow shaft-shaped part, and rotates around a shaft center thereof during opening and closing actions; and a valve seat having a sloped seat surface with which the closure part of the poppet comes into contact when closing the valve device. The closure part of the poppet or the seat surface of the valve seat, whichever has a higher hardness, has a cut mark of the opposite direction from a direction of rotation of the poppet around the shaft center that occurs during the valve closing action.
