The cross-flow fan blade comprises a plurality of fan blade sections arranged in sequence, two opposite surfaces of any two adjacent fan blade sections are a first matching surface and a second matching surface respectively, the first matching surface is provided with a matching groove, the second matching surface is provided with a clamping structure, the clamping structure is clamped in the matching groove, and the clamping structure is clamped in the matching groove. And every two adjacent fan blade sections are fixedly connected. By the adoption of the scheme, two adjacent fan blade sections can be fixedly connected through clamping of the clamping structures and the matching grooves, and therefore the cross-flow fan blade is formed through combination. According to the scheme, ultrasonic welding connection of the fan blade sections is replaced, special equipment and complex processes are not needed, assembly is convenient, and therefore the cost of the cross-flow fan blade is reduced. 本发明提供了一种贯流风叶及空调器，贯流
