たものが知られている。2. Description of the Related Art It is said that it is preferable to use a flexible heating wire and use a metal foil soaking plate as a whole in such a conventional planar heating device. However, when a voltage is applied to the heating wire, an induced voltage is generated in the metal foil by electrostatic induction. When the contact area between the metal foil and the heating wire exceeds a certain area, the capacitance also increases, and the charge at the time of discharge also increases. There were problems such as electric shock. Thus, as shown in FIG. 5, in a heat equalizing adhesive sheet 3 in which an adhesive film 2 is laminated on both sides of a metal foil heat equalizing plate 1, a portion of only the adhesive film 2 without the metal foil is an end portion (hereinafter, referred to as an end portion). The heat equalizing plate 1 is overlapped so that the portions of the heat equalizing plate 1 do not overlap with each other. What bonded together by heat is known.

とは言えないといった課題を有していた。Problems to be Solved by the Invention However, in the above configuration, due to the tension generated when the adhesive film 2 is laminated on the metal foil used as the heat equalizing plate 1, the adhesive film 2 is slightly elongated by the tension, Since the heat equalizing plate 1 is made of metal, there is almost no elongation. Due to the difference in elongation generated between the two, the ear portion 4 shrinks after completion of the heat equalizing adhesive sheet 3, and as shown in FIG. > Y and wrinkles appear toward the ears 4. Due to these dimensional changes and wrinkles, quality problems such as appearance problems, variations in heater unit production, and destruction of waterproofness and insulation performance are likely to occur. However, there was a problem that it was not efficient in terms of cost and workability.

どが考えられる。In FIGS. 1 and 2, a flexible heating wire 12 is bonded to at least one surface of a heat equalizing adhesive sheet 11 to form a heater unit. The heat equalizing adhesive sheet 11 is located between the outer cloth 13 and the heat insulating material 14, and is integrally bonded by heat. In detail, the heat equalizing adhesive sheet 11 divides the metal heat equalizing plate 15 into a plurality of pieces, and adheres a single heat-meltable adhesive film 16 to both surfaces of the plurality of heat equalizing plates 15 with the adhesive 17. To form a uniform heat bonding sheet 11. In this case, the outer peripheral end faces of the two hot-melt adhesive films 16 are
The end face of the heat equalizing plate 15 is made to coincide with the end face. A flexible heating wire 12 is adhered to at least one surface of the heat equalizing adhesive sheet 11. The material of the heat equalizing plate 15 was aluminum foil, the interval A between the divided adjacent heat equalizing plates 15 was 2 to 20 mm, and was smaller than the wiring pitch B of the flexible heating wires 12, and A <B.
The heat-melt adhesive film 16 was made of polyethylene on one side of the soaking plate 15 and polyester on the other side. However, as this material, for both films, olefin-based, ester-based, and olefin-based resins obtained by graft-polymerizing vinyl chloride can be considered.

トはそのまま端部を重ね合わせていけばよい。In the above configuration, the heat equalizing plate 15 can be divided into the heat equalizing adhesive sheet 11, and there is no need to provide ears without the heat equalizing plate on both side surfaces of the heat equalizing adhesive sheet 11. Even without using a plurality of sheets, the area of the metal foil can be reduced, and the capacitance can be reduced. Also, FIG.
As shown in FIG. 4, shrinkage due to the tension of only the heat-meltable adhesive film 16 in the heat equalizing adhesive sheet 11 hardly occurs due to the heat equalizing plates 15 on both sides serving as a base material. Therefore, there is an effect that wrinkles and dimensional changes do not occur, and a stable and high-quality heater unit having high waterproofness and insulation properties can be obtained. It should be noted that there is no problem in using a plurality of heat equalizing adhesive sheets as needed. At this time, the ends of the adhesive sheet may be overlapped as they are.
