PROBLEM TO BE SOLVED: To provide a method for manufacturing a support body having a structure in which a support substrate and metal foil can be easily separated and the like.SOLUTION: A method for manufacturing a support body includes the steps of: arranging an adhesive force adjustment layer for adjusting a contact area of a support substrate and a peeling layer in a predetermined region excluding an outer peripheral part on the support substrate; and arranging metal foil in which the peeling layer is formed on one surface thereof on the adhesive force adjustment layer and the outer peripheral part of the support substrate in the state in which the peeling layer is oriented to the side of the support substrate, and temporarily bonding the outer peripheral part of the support substrate and the peeling layer in a peelable manner. In the step of temporary bonding, the support substrate and the adhesive force adjustment layer are bonded, and the peeling layer and the adhesive force adjustment layer contact with each other without bonding.

PROBLEM TO BE SOLVED: To provide a printed wiring board excellent in insulating layer adhesiveness, and a manufacturing method thereof.SOLUTION: A printed wiring board comprises an insulating substrate, a metal wiring disposed on the insulating substrate, and an insulating layer disposed on the metal wiring. On this printed wiring board, a thiol compound layer having four or more functional groups represented by a formula (1) intervenes in an interface between the metal wiring and the insulating layer. (In the formula (1), * represents a binding position.)

PROBLEM TO BE SOLVED: To provide a paste composition which can inhibit corrosion of a conductor layer by formic acid, and a wiring circuit board using the same.SOLUTION: A conductor layer 3 is formed on one surface of a base insulating layer 2. The conductor layer 3 includes a pair of rectangular collector portions 3a, 3b and drawn-out conductor portions 4a, 4b extending in an elongated shape from the collector portions. cover layers 6a, 6b are formed on the base insulating layer 2 so as to cover a predetermined portion of the conductor layer 3. A paste composition containing a compound expressed by formula (1) is used as the material for the cover layers 6a, 6b (wherein R1 and R2 are the same or different, and are each hydrogen or a substituent group).
