The flow regulating device has a shape preservation member which surrounding the environment of a flow conduit and restricts the amount of heat deformation of a housing in the housing. The shape preservation member is made from a material whose amount of heat deformation is lower than that of the housing. Furthermore, the shape preservation member includes a first metal plate member positioned on one side of the flow conduit, a second metal plate member positioned on the other side of the flow conduit, a spacer which maintains a constant interval between the first and second plate members, and bolts which fix together the first and second plate members via the spacer. In this flow regulating device, while maintaining excellent chemical resistance by making a housing from resin, accurate flow amount regulation over a wide temperature range can be performed.
