ABSTRACT:
The present invention relates to a printed circuit board and a printed circuit board base material for use in the printed circuit board. The printed circuit board base material of the present invention is produced by impregnating a carbon core material such as carbon cloth with a first resin such as epoxy resin, and the printed circuit board of the present invention is characterized in that resin pores are opened on the printed circuit board base material, second resins such as epoxy resins are filled in the resin pores, circuit layers are formed on the printed circuit board base material, through holes connecting the circuit layer together are provided, and the center line of the resin pore is approximately in line with the center line of the through hole.
