A heater for an airbag device includes a sheet-shaped heater body including a heat generation unit, and disposed to cover a vehicle interior surface side of an airbag cover and configured to generate heat to emit the radiation heat. The heater body is formed of a flexible woven fabric including a warp and a weft, and is provided with a dividing scheduled portion configured to be divided at a time of opening of a door portion at a position corresponding to the breakage scheduled portion formed in the airbag cover. The dividing scheduled portion is provided with, substantially along the breakage scheduled portion, main slits that are intermittently provided and sub slits disposed on at least one side of the main slits. The sub slits are disposed in the woven fabric to cut the warp or the weft implementing a portion of a coupling portion formed between the main slits.
