  • the body tries to displace in the direction of arrow AR2b, which is opposite to arrow AR2a. That is, the surface layer portion 14 easily follows the expansion of the heat generating portion 12 near the slit 20B. In this case, thermal stress due to the difference in linear expansion coefficient between the heat generating portion 12 and the surface layer portion 14 is relaxed, making it difficult for unintended deformation DF such as unevenness and wrinkles to occur on the heater surface 10a.
  • the heater device 1 of this embodiment can obtain the same effects as the first embodiment from the same configuration or equivalent configuration as the first embodiment.
  • the plurality of slits 20B are provided in the surface layer portion 14 of the laminate ST. According to this, thermal stress due to the difference in linear expansion coefficient between the heat generating portion 12 and the surface layer portion 14 can be alleviated by the plurality of slits 20B provided in the surface layer portion 14. As a result, it is possible to suppress unintended deformation DF due to differences in linear expansion coefficients of each member of the laminate ST.
  • the slit 20B is provided in the surface layer portion 14, but the slit 20B is not limited thereto.
  • a plurality of slits 20A may be provided not only in the surface layer portion 14, but also in the heat generating portion 12, or a plurality of slits 20 may be provided in the heat insulating portion 16, for example.
  • the plurality of slits 20B may be formed in the manners shown in the second to fifth modifications of the first embodiment.
  • the components of the heater device 1 have been specifically described, but some of the components of the heater device 1 may be different from those described above.
  • the heater main body 10 may have a shape other than a rectangular shape.
  • the heater main body 10 of the above-described embodiment includes the case portion 18, the case portion 18 is not an essential component and may be omitted. Further, although the heater main body 10 in the above-described embodiment is installed on the steering column SC, the heater body 10 is not limited thereto, and may be installed on, for example, an instrument panel, a glove box, the back of the backrest of the seat S, etc. Good too.
  • the heater device 1 of the present disclosure is applied to a heating device that warms the interior of a vehicle, but the heater device 1 of the present disclosure is applicable to a heating device that warms an indoor space, a portable heating device, etc. It is also widely applicable.
