Zusammenfassung:A differential-pressure flow sensor and a ventilator. The differential-pressure flow sensor comprises a main body (100) and a honeycomb structure (200). The main body (100) is provided with a flow channel (101) for air to circulate therein, wherein the flow channel (101) comprises an inflow section (102), an outflow section (103), and a throttling section (104) that communicates the inflow section (102) with the outflow section (103). The honeycomb structure (200) is mounted in the throttling section (104), wherein several through holes (201) are formed in the honeycomb structure (200), or the several through holes (201) are formed in the honeycomb structure (200) itself and in inner walls of the honeycomb structure (200) and the throttling section (104); the several through holes (201) are respectively in communication with the inflow section (102) and the outflow section (103); and any two adjacent through holes (201) share one through hole (201) wall. Any two adjacent through holes (201) share one through
