Abstract:
1. A paste composition containing an inorganic filler, a resin, a compound having a phosphoric ester skeleton and a solvent, wherein the paste composition is characterized in that it contains one or more solvents of which the boiling point is 160° C. or higher and an inorganic filler of which the mean particle diameter is 5 μm or smaller, the inorganic filler is at least one selected from the group consisting of a barium titanate, a barium zirconate titanate, a strontium titanate, a calcium titanate, a bismuth titanate, a magnesium titanate, a barium neodymium titanate, a barium tin titanate, a barium magnesium niobate, a barium magnesium tantalate, a lead titanate, a lead zirconate, a lead zirconate titanate, a lead niobate, a lead magnesium niobate, a lead nickel niobate, a lead tungstate, a calcium tungstate, a lead magnesium tungstate, and a titanium dioxide, the content of the inorganic filler is 85 wt % or more and 99 wt % or less based on the total amount of the solid component contained in the paste composition, and the total content of the solvent being 25 wt % or less based on the total amount of the paste composition, and the resin being a thermosetting resin selected from the group consisting of a polyimide resin and an epoxy resin, and when the thermosetting resin is an epoxy resin, the paste composition further contains a curing accelerator or a curing accelerator and a curing agent.
