PURPOSE:To obtain performance different from the same conical paper by sticking the conical faces of two kinds or more of conical paper produced under different conditions. CONSTITUTION:The conical paper 1 is obtained by applying a binding agent to a joining part 2 of different conical faces 1a, 1b having different conditions such as cone materials, smashing degrees and forming conditions and pressing the joining part to unitedly form both the conical faces 1a, 1b. Consequently, a high frequency part can be improved.
