Abstract:
1. A heat-resistant resin paste, comprising a first organic solvent (A1), comprises a nitrogen-containing cyclic compound having polarity, a second organic solvent (A2) containing a lactone, wherein the lactone is δ-butyrolactone, a heat-resistant resin (B) soluble in the first organic solvent of (A1) or a mixed solvent of the first organic solvent (A1) and the second organic solvent (A2), a heat-resistant resin filler (C) insoluble in the mixed solvent of the first organic solvent (A1) and the second organic solvent (A2), and a pigment (D), wherein the pigment (D) is a powder which is white in color of titanium dioxide, wherein the heat-resistant resin filler (C) and the pigment (D) are dispersed in a solution containing the first organic solvent (A1), the second organic solvent (A2), and the heat-resistant resin (B), wherein the heat resistant resin filler (C) comprises a polyimide resin, a polyamideimide resin, a polyamide resin, or a precursor thereto.
