摘要： An aerosol generating device and a heater (30) therefor are provided. The aerosol generating device includes: a chamber, configured to receive an aerosol generating product (A); and a heater (30), configured to be inserted into and heat the aerosol generating product (A). The heater (30) includes a free front end (310) and a tail end (320) away from the free front end (310). The heater (30) includes: a base body (31), extending between the free front end (310) and the tail end (320) in a length direction of the heater (30); a resistance heating coil (32), surrounding the base body (31); and a protective coating (34), wrapping at least a part of the resistance heating coil (32) and maintaining the resistance heating coil (32) outside the base body (31). In the foregoing aerosol generating device, the protective coating (34) is formed outside the base body (31) that is surrounded by the resistance heating coil (32), and the resistance heating coil (32) is limited, wrapped, or fixed by the protective coating (34), so that the resistance heating coil (32) is maintained outside the base body (31), to prevent the resistance heating coil (32) from getting loose from or moving on the base body (31).
