[0002]

2. Description of the Related Art Conventionally, a method for producing a laminated body for producing a printed wiring board, an IC card or the like has been disclosed in Japanese Patent Publication No. 8-506.
Known by No. 288. In this conventional example, a sheet made of a stainless steel sheet is laminated between the copper layer on the upper surface of the unit laminate and the copper layer on the lower surface of the upper unit laminate, and the copper layers of each stage are electrically connected. Connected by wiring, connecting the first copper layer and the last copper layer of the laminated body manufacturing block to an electric current source by an electric lead wire, pressurizing the laminated body manufacturing block and energizing the copper layer to heat the copper layer As a result, the sheet-like synthetic resin material of each unit laminate is closely adhered to the copper layer.

[0003]

However, in the above-mentioned conventional example, since the copper layers of each stage are connected by the electric wiring, the unit laminates are laminated vertically in multiple stages to form a laminate production block. It takes time to configure, and in connecting the copper layers of each stage with electric wiring, if the connection is not reliable, uniform heat generation of the copper layer in each stage cannot be achieved, and
If the copper layers are connected in advance by electric wiring, the electric wiring may be broken during the lamination process. Further, in the above-mentioned conventional example, when the laminated body to be formed is thin, the copper layers are likely to come into contact with each other, and a portion that does not generate heat is generated in the copper layer, and the sheet-shaped synthetic resin material and the copper layer cannot be adhered to each other. There are cases.

The present invention has been made in view of the above-mentioned problems of the conventional example, and can shorten the manufacturing time of a laminated block for manufacturing a laminated body, and can also fold up and down adjacent strip-shaped metal members. It is an object of the present invention to provide a method for manufacturing a laminate and an apparatus therefor capable of easily and surely adhering metal layers to both sides of a sheet-shaped synthetic resin material without the possibility of mutual contact.

As a result, the heat generation in each part of the strip-shaped metal material 5 becomes uniform, and the sheet-shaped synthetic resin material 1 and the metal layer 2 can be brought into close contact with each other even more. Further, since the continuous strip metal material 5 acting as an electric heating element does not directly form a laminate, the continuous strip metal material 5 can be freely selected.

Further, it is preferable that the insulating intermediate plate 4 is constructed by providing a layer 7 having a high electrical insulating property on the side of the metal intermediate plate 4a facing the metal layer 2, whereby a pair of insulating intermediate plates is formed.
