Abstract
A thin-plate-like flexible carbon plate having flexibility, excellent compressive strength, and even electrical conductivity is provided. A carbon plateis a carbon plate having a thickness of 0.05 to 2.0 mm obtained by compression molding of a mixture of (a) 97 to 80 wt % carbon powder composed of 95 to 30 wt % expanded graphite powder and 5 to 70 wt % graphite powder, and (b) 3 to 20 wt % phenolic resin that do not contain ammonia, wherein a compressive strength is 3 MPa or more, a bending strain is 0.6% or more without a crack, and a contact resistance is 6 mΩ·cmor less.
