The carbon nanotubes are dispersed on the surface of the substrate 111 so as to extend around the surface of the substrate 111.
カーボンナノチューブは、単体では肉眼では識別できないほど細い部材である。カーボンナノチューブは、透過性を有する密度で基材１１１に配置されている。透過性を有する密度とは、その密度でカーボンナノチューブだけを配置したと仮定した場合、反対側が透けて見えるような密度のことを意味している。
A carbon nanotube is a thin member so that it can not be recognized by the naked eye alone. The carbon nanotubes are arranged on the substrate 111 at a density having permeability. Permeable density means the density at which the opposite side can be seen through, assuming that only carbon nanotubes are arranged at that density.

In other words, the heat generating portion 112 of the seat heater 11 is provided on the seat 2 so as to touch the occupant. According to the present embodiment, it is possible to reliably give the occupant a warm feeling.
シートヒータ１１の基材１１１が透明であり、発熱部１１２に、カーボンナノチューブが透過性を有する密度で配置されていれば、シートヒータ１１のほぼ全体が透明になるので、意匠性が向上する。すなわち、シートヒータ１１が座面部２ａの表皮の表面に貼られていても座面部２ａの表皮がシートヒータ１１越しに透けて見えるので、シートヒータ１１が座面部２ａの表皮の意匠を損なうことを抑制できる。
If the base material 111 of the seat heater 11 is transparent and the carbon nanotubes are disposed at the heat generating portion 112 at a density having transparency, almost the entire seat heater 11 becomes transparent, and the designability is improved. That is, even if the seat heater 11 is attached to the surface of the skin of the seat portion 2a, the skin of the seat portion 2a looks through through the seat heater 11, so that the seat heater 11 loses the design of the skin of the seat portion 2a. It can be suppressed.
