Abstract
A valve device includes: a valve member that controls flow of a fluid, and a body that has a valve insertion hole in which the valve member is inserted, and whose inner surface is cylindrically formed, and into which the fluid flows, and a lead-in passage that has an opening in the inner surface of the valve insertion hole, and that causes the fluid to flow into the valve insertion hole. A line representing the direction of extension of the lead-in passage is tilted from a line normal to the inner surface of the valve insertion hole at a position of the opening of the lead-in passage, in a view in the axis direction of the valve insertion hole.
