A novel conductive paste is disclosed which is suitable for use to connect circuit patterns of a printed circuit board.The conductive paste comprises a melt of gallium and a metal element which forms an eutectic mixture with gallium, and metal powder which alloys with gallium uniformly dispersed in the melt. The content of the metal element and the metal powder are selected to control a solid content in the paste at a predetermined working temperature.

To increase the dimensional accuracy of an interlayer member used for producing a multilayer wiring board which is inserted between two wiring layers to establish interlayer insulation and interlayer electrical connection between the wiring layers, to thereby increase a layout density. A mask film is formed on a main surface of a sheet-like carrier layer. A metal column for interlayer connection is formed on the main surface of the carrier layer by plating a copper using the mask film as a mask. The mask film is removed. An interlayer insulating layer and a protective sheet are laminated on the main surface of the carrier layer in such a manner that the metal column for interlayer connection penetrates them. The interlayer insulating layer and the protective sheet are polished until the upper surface of the metal column for interlayer connection is exposed. Then, the carrier layer is removed. Furthermore, the protective sheet is removed.

At a cut end portion of a belt-like member is formed a jointing surface, which is inclined at a small angle with respect to the surface of the belt-like member, simultaneously with cutting. A belt-like member (32) on a conveyor belt (6) is pinched under a pressure by an upper die (29) and a lower die (33) heated respectively by heaters (30) and (34), thereby it is subjected to plastic deformation and cut, and also jointing inclined surfaces are formed at the cut end portions. A die holding member (24) for holding the upper die is reciprocated in the vertical direction, by an action of a rotary shaft (11) having an eccentric cam (18). A separating member (38) which is moved vertically by another cam (40) operates as delayed with respect to the movement of the upper die, and when the upper die leaves the belt-like member, it presses the belt-like member to insure separation of the die.
