Abstract
A plate-shaped carbon fiber-reinforced carbon composite has a longitudinal length-to-widthwise length ratio of more than 1. The carbon fiber-reinforced carbon composite is such that at least two layers that are a first carbon fiber-reinforced carbon composite layer in which carbon fibers are placed in the carbonaceous matrix and are oriented in the longitudinal direction and a second carbon fiber-reinforced carbon composite layer different in the arrangement of the carbon fibers from the first carbon fiber-reinforced carbon composite layer are stacked, the first carbon fiber-reinforced carbon composite layer forms an outermost layer of at least one plate surface, the thickness thereof is 70% or more of the thickness of the carbon fiber-reinforced carbon composite, and the longitudinal bending elastic modulus is 150 GPa or more. The first carbon fiber-reinforced carbon composite layer in which the carbon fibers are aligned in the longitudinal direction is placed only on an outermost layer of one or both of plate surfaces and another site is a carbon fiber-reinforced carbon composite layer different in the arrangement of the carbon fibers from the first carbon fiber-reinforced carbon…
