<p>A flow velocity detector, wherein an upstream side temperature sensor (3U1) and a downstream side temperature sensor (3D1) are disposed on both sides of a heater (2-1) with the recessed and projected direction of the heater (2-1) in comb tooth-shape positioned approximately in parallel with the flow direction A of a detected fluid, whereby heat from the heater (2-1) first heats the crank-shaped connection parts (J) of the temperature sensors (3U1, 3D1) in comb tooth shape, respectively, and then transfers through straight line parts (S) along the crank-shapes in the direction approximately in parallel with the flow direction of the detected fluid.</p> |
