PURPOSE:To enhance heat resistance of a porous fluororesin base material and to obtain an excellent fluororesin base material to be used as a material for a printed circuit board by adhesively coupling a special carbon material in the pores of the base material. CONSTITUTION:A fluororesin base material in which fluorine-containing carbon material is adhesively coupled in the pares of a porous fluororesin base material. As the fluorine-containing carbon material includes, for example, graphite, fluorinated pitch, etc. |
