摘要： A flow measurement device according to the present invention includes a main flow channel through which fluid flows, and a secondary flow channel unit where the fluid is diverted from the main flow channel, supplied to a flow amount detection element and thereafter returned to the main flow channel. The secondary flow channel unit includes a diversion flow channel through which the fluid is diverted from the main flow channel and returned to the main channel without the fluid being supplied to the flow amount detection element, and a detection channel in which the fluid is diverted from the diversion flow channel and provided to the flow amount detection element. The diversion flow channel includes a smooth flow part in which the fluid flows smoothly between the two ends connecting to the main flow channel, and a first chamber and a second chamber which, adjacent to the smooth flow part, are divided by a partition provided so as to obstruct flow of the fluid. The two ends of the detection channel are connected to the first chamber and the second chamber.
