2. Description of the Related Art From the point of view of downsizing of circuit structure, downsizing and large capacity of circuit structure, so-called printed wiring board is required.
Mounted circuit devices that are mounted and mounted with various electronic components are widely put to practical use. By the way, in this type of printed wiring board, the mounting surface of electronic parts is flush with the adjacent insulating area surface from the viewpoints of increasing the mounting and mounting density of electronic parts, and maintaining stable mounting. It is hoped that A printed wiring board that meets such a demand is manufactured by the following means. The first means (method) is to prepare a laminated plate having an adhesive layer on its main surface, form a required through hole at a predetermined position of this laminated plate, and then coat a permanent plating resist pattern of an inverse circuit pattern. After depositing and forming, a required circuit pattern is formed by a so-called full additive method such as chemical copper plating. The second means (method) is
A photosensitive dry film is attached to a stainless steel plate surface having a smooth main surface, and selective exposure / development processing is performed to form an image of a reverse circuit pattern. Next, a step of laminating, in which a copper electroplating treatment is performed using the stainless steel plate as one electrode to form a required circuit pattern, the photosensitive dry film is peeled off, and then a laminated wiring board is manufactured. Then, the circuit pattern is formed on the surface of the prepreg layer or the like by a so-called transfer method in which the circuit pattern is transferred from the stainless plate surface.

However, the above-mentioned method of manufacturing a printed wiring board has the following practical problems. That is, in the case of the first means, it is necessary to use a chlorine-based organic solvent in the step of developing the permanent plating resist pattern, the step of removing the permanent plating resist pattern layer, and the like, so that not only is there a problem in terms of safety and hygiene. When forming a circuit pattern by the full-additive method, it is difficult to control the plating solution to achieve the required thickness, and the plating process requires a relatively long time (usually 10 hours or more). There is. Further, the second means is effective when forming the circuit pattern of the outermost layer, but not only the process becomes complicated when the inner layer circuit pattern is also transferred and formed, but also a continuous manufacturing process is adopted. In addition, it is difficult to connect the through holes after lamination, and the inner wall surface of the through holes that have been drilled is plated again to form the required plating layer (partial additive method).
It cannot be said to be mass-produced because it needs to be done.

1. A photosensitive resin layer is formed on the main surface of a conductive supporting substrate having good peelability and smoothness, and the photosensitive resin layer is selectively exposed and developed to form a plating resist pattern layer having a reverse circuit pattern. A step of forming a predetermined circuit pattern by performing electrolytic copper plating on the exposed main surface of the conductive support substrate having the plating resist pattern layer formed on one electrode side, and removing the plating resist mask And then again forming a photosensitive resin layer, selectively exposing and developing, and then performing at least chemical copper plating to form a copper plating layer; and selecting a releasable resist layer by laminating on the copper plating layer forming surface. Exposing and developing to form a reverse circuit pattern, and after forming the reverse circuit pattern composed of the peelable resist layer, at least an electroplating layer and a solder plating layer A step of sequentially forming, the peelable resist pattern is peeled and removed, and the copper plating layer formed by performing at least the chemical copper plating treatment exposing the solder plating layer as an etching resist layer is selectively removed by etching. After forming the circuit pattern layer, removing the solder plating layer, forming a photosensitive resin layer on the circuit pattern layer forming surface, forming a reverse circuit pattern by selection / exposure, and then at least a chemical copper plating layer. Circuit, the formation of a peelable resist pattern, the sequential formation of an electroplating layer, the peeling removal of the peelable resist pattern, and the selective etching removal of at least the chemical copper plating layer using the solder plating layer as an etching resist layer. The step of repeating the pattern layer formation and the removal of the solder plating layer, and the conductive support of the laminated body of the circuit pattern. A method for manufacturing a printed wiring board, comprising the step of peeling from a substrate surface.
