PROBLEM TO BE SOLVED: To provide a carbon paste which can be cured at high temperatures and does not have discoloration even if cured at high temperatures and can demonstrate a sufficient adhesion strength, and of which electrical resistance can be decreased sufficiently. SOLUTION: This is the carbon paste 1 which contains spherical and flaky graphite powders 11, 12 and acetylene black as a conductive material, and contains polyester silicon resin 15 as a vehicle. The carbon paste 1 contains 15-25 pts.wt. of spherical graphite powder, 15-25 pts.wt. of flaky graphite powder, 10-20 pts.wt. of acetylene black, and 40-55 pts.wt. of polyester silicon resin 15. Then, the spherical and the flaky graphite powders 11, 12 have the average particle size of 10μm-20μm. COPYRIGHT: (C)2005,JPO&NCIPI
