Abstract (en)

[origin: EP4111888A1] Disclosed are an electronic atomization device, an atomization assembly (100), an atomization element (40) and a manufacturing method therefor. The atomization element (40) comprises a porous matrix (42) and a heating layer, wherein the porous substrate (42) is provided with an atomization surface (422); and the heating layer covers the atomization surface (422). The heating layer comprises a conductive layer (44) and a stable layer (46), wherein the conductive layer (44) covers the atomization surface (422); and the stable layer (46) covers the surface of the conductive layer (44) away from the porous matrix (42). The resistivity of a material for preparing the stable layer (46) is lower than that of the conductive layer (44), and the oxidation resistance of the stable layer (46) is higher than that of the conductive layer (44), so as to solve the problem of the resistance value of the conductive layer (44) rising too quickly.
