Abstract

To provide a heater for an airbag device which can also be used in an existing airbag device and suppresses an increase in manufacture cost or the like.SOLUTION: A heater for an airbag device includes a sheet-type heater body 55 disposed to cover a cabin inside surface side of an airbag cover of an airbag device. The heater body is formed of a woven fabric 56 having flexibility, and has heat dissipation means. A division planned part 58 capable of being divided when a door part is opened is disposed at a position corresponding to a rupture planned part of the airbag cover. The division planned part includes: a main slit 59 intermittently provided substantially along the rupture planned part; and sub slits 60 disposed on the sides of the main slit. The sub slits are disposed in the woven fabric so as to break warp yarns VT or weft yarns HT which constitute a portion of a coupling part 62 formed between parts of the main slit.SELECTED DRAWING: Figure 7
