Claim:
1. A method for manufacturing a structure containing a conductor circuit on a surface of a support and a heat-curable resin layer as an insulating layer having at least one opening through which the conductor circuit is exposed so that a wiring portion may be formed in the opening connected to the conductor circuit, the method comprising: a first photosensitive resin layer formation process for forming a first photosensitive resin layer to cover the conductor circuit on the support; a first patterning process for patterning the first photosensitive resin layer by performing an exposure process and a developing process on the first photosensitive resin layer; a heat-curable resin layer formation process for forming a heat-curable resin layer on the support to cover the pattern of the first photosensitive resin layer; a heat-curing process for heat-curing the heat-curable resin layer as a process immediately after the heat-curable resin layer formation process, a material removal process for removing a portion of the heat-curable resin layer to expose a predetermined place of the pattern of the first photosensitive resin layer from the heat-curable resin layer, wherein the material removal process comprises performing removal of a portion of the heat-curable resin layer after the heat curing by performing plasma processing; and an opening formation process for removing the first photosensitive resin layer exposed from the heat-curable resin layer by a desmearing process to form an opening through the heat-curable resin layer exposing the conductor circuit.
