する。 The structure of the sheet-like heater unit 9 of the present invention will be explained below with reference to FIGS. 3 to 8.
FIG. 3 is a perspective view of the sheet-like heater unit 9 of the present invention. This sheet-shaped heater unit 9
As shown in FIG. 4, a heating wire 16 is arranged in a meandering manner on a core body 17 made of a single sheet of needle-punch type non-woven fabric so as to have good bending characteristics, and a cord 12 is connected to the cord 12 by a cord connecting portion 21. Connect the code 12
A connector 13 is connected to the tip. The heating wire 16 of the core body 17 is disposed using a jig, and the inner cloth bodies 15 and 18 having a small basis weight are primarily bonded from above and below using a hot press. The inner cloth bodies 15 and 18 include
As shown in Figure 5, PE, polyamide,
A thermobonding resin 20 such as PYC is attached in dots, which are melted by heat and bonded to the core body 17. When the jig is removed at the same time as the hot pressing, the result is as shown in FIG. The core body 17 is made of elastic needle-punch type nonwoven fabric and is arranged so that the heating wire 16 is sunk.
To eliminate the feeling of a foreign body on the surface due to the protrusion of the heating wire 16.
