記の金属箔３をリード線７で接続していた。This figure is an enlarged cross-sectional view of the main part of a conventional electric heating mat.
A metal foil 3 and a surface material 4 were laminated on top of the metal foil 3 and a surface material 4 were attached thereto, and a grounding terminal 6 attached to a power source N5 and the metal foil 3 were connected by a lead wire 7.
（発明が解決しようとする課題）
しかしながら、上記の構成では、金属箔３が発熱線２の
上側に設けられているので、下側から針などが発熱線２
に刺さった場合には、アースの目的を全うできず、刺さ
った針に触れると感電する危険性があるという問題があ
った。(Problem to be Solved by the Invention) However, in the above configuration, since the metal foil 3 is provided above the heating wire 2, a needle or the like is inserted into the heating wire 2 from below.
If the needle sticks into the needle, the purpose of grounding cannot be fulfilled, and there is a risk of electric shock if one touches the needle.
また、上記のリード線７は、金属箔３にはんだによって
接続されているため、接続部が弱く断線し易いという問
題もあった。また、断熱材１に配線溝１ａを形成するた
め、高価になるという問題もあった。Further, since the lead wire 7 is connected to the metal foil 3 by solder, there is a problem that the connection portion is weak and easily breaks. Furthermore, since the wiring grooves 1a are formed in the heat insulating material 1, there is also a problem that the cost becomes high.
本発明は上記の問題を解決するもので、針等が刺さって
も感電を起こさずまた、断線の起きない信頼性の高い安
価な電熱マットを提供するものである。The present invention solves the above-mentioned problems and provides a highly reliable and inexpensive electric heating mat that does not cause electric shock even if it is penetrated by a needle or the like, and does not cause disconnection.
（課題を解決するための手段）

露呈させた金属箔にリード線を取り付けるものである。(Means for Solving the Problems) In order to solve the above problems, the present invention provides a flat heating wire whose top and bottom are covered with metal foil between an elastic heat insulating material and a flexible surface material. In addition, the lead wires are attached to metal foils that are exposed by cutting out the ends of the heat insulating material and the surface material in the same U shape.
（作 用）
上記の構成により、発熱線の上下が金属箔で覆われてい
るので、いずれの方向から刺さっても、感電が回避でき
る。(Function) With the above configuration, since the top and bottom of the heating wire are covered with metal foil, electric shock can be avoided even if the heating wire is penetrated from any direction.
また、リード線は、金属箔に、表裏から挾持して接続さ
れるので、強固でちぎれにくく従って、断線の心配がな
くなる。Further, since the lead wire is connected to the metal foil by being sandwiched from the front and back, it is strong and hard to tear, so there is no need to worry about disconnection.

同一符号を付した。Figures 1 and 2 are a plan view and a sectional view taken along line A-B-C-D of the electric heating mat according to the present invention, and Figures 3 and 4 are views of the main parts of the electric heating mat according to the present invention. FIG. 5 is a plan view and an enlarged perspective view of the main part showing the connection part, and a cross-sectional view of the main part showing the state where it is attached to the floor. In FIG. 2, this embodiment differs from the conventional example shown in FIG. Aluminum metal foil on both sides 3
The exposed portions of the metal foils 3a and 3b are shown in FIG. The point is that the lead wire 7 inserted through is soldered from both sides. Since the rest is the same as the conventional example, the same components are given the same reference numerals.

通して発熱線２に触れても、電流は、抵抗の少ない金属
箔３ａあるいは３ｂからリード線７を介しアース用端子
６にアースされているため、電気抵抗の大きい人体を流
れることはなくなる。In this embodiment, when installing the electric heating mat, even if a metal object such as a needle penetrates the heat insulating material 1, the surface material 4, and the metal foil 3a or 3b and touches the heating wire 2, the current will flow through the heating wire 2, which has a low resistance. Since the metal foil 3a or 3b is grounded to the grounding terminal 6 via the lead wire 7, it will not flow through the human body, which has a large electrical resistance.
このように、いずれの方向から針等の金属物が刺っても
感電を回避できる。In this way, electric shock can be avoided even if a metal object such as a needle sticks from any direction.
また、リード線７は、２枚の金属箔３ａあるいは３ｂを
挾みつけて取り付けられているので、金属箔３ａあるい
は３ｂに外力に加わってもちぎれにくい。Further, since the lead wire 7 is attached by sandwiching the two metal foils 3a or 3b, it is difficult to tear off even if an external force is applied to the metal foils 3a or 3b.

暖房効果が得られる。従って、発熱線２の耐久性が向上
する。In addition, since the lower side is also covered with metal foil 3b, the foundation floor 8
Not only is heat radiation to the heating wire 2 prevented, but heat conduction from the heating wire 2 is improved, so even if the heating wire 2 is kept at a low temperature, the same heating effect can be obtained. Therefore, the durability of the heating wire 2 is improved.

熱線２を覆う表面材４の部分が、強く床仕上材９に接触
するので、床仕上材８への熱伝導効率も向上する。Furthermore, as shown in FIG. 5, the heating wire 2 rests on the metal foil 3b spread over the elastic heat insulating material l, so that the force that lifts the heating material 2 upward is exerted. Since the portion of the surface material 4 that covers the heating wire 2 strongly contacts the floor finishing material 9, the heat conduction efficiency to the floor finishing material 8 is also improved.
（発明の効果）
以上のように、本発明によれば、電熱マットを設置する
際に、誤って針などの金属物が刺っても感電を起こさず
、リード線の取付けが強固なので断線が生じない、信頼
性が高く安全で然かも安価な電熱マットが得られる。(Effects of the Invention) As described above, according to the present invention, even if a metal object such as a needle accidentally pierces an electric heating mat when it is installed, an electric shock will not occur, and the lead wires will not be disconnected because they are firmly attached. A highly reliable, safe, and inexpensive electric heating mat that does not generate heat can be obtained.
さらに、基礎床への熱損失が少さく、床仕上げ材への熱
伝導効率が良い、消費電力の少ない耐久性に優れた電熱
