The invention discloses an LED filament. The LED filament comprises multiple LED chips, at least two electrodes and a light conversion layer, wherein the multiple LED chips are electrically connected with the at least two electrodes, the light conversion layer has a top layer and a base layer, the top layer and the base layer are respectively arranged at at least two sides of the multiple LED chips and the at least two electrodes, and parts of the two electrodes are exposed by the light conversion layer. The LED filament is advantaged in that the light conversion layer has a multi-layer layered structure, layered adjustment on hardness, light transmittance and a refractive index can be realized, so hardness, light transmittance and the refractive index of the LED filament can be adjusted to an optimum state, and the LED filament can be made to satisfy different demands of LED bulb lamps.
