A hot wire type flow sensor having a cylindrical housing to be placed in a fluid passage, a plurality of hot wire supporters mounted on the inner surface of the housing, a hot wire stretched between the supporters, and a control circuit connected to the hot wire to output a signal in proportion to a flow rate of fluid. The inner surface of the housing at the upstream side of the hot wire is so formed that the flow of the fluid is concentrated at the central part of the hot wire.
