CARBON HEATER AND METHOD OF MANUFACTURING CARBON HEATER

Japanese Patent JP2017103190

A

PROBLEM TO BE SOLVED: To provide a carbon heater that has an accurate resistance value, a uniform heat generation distribution and a long lifetime, and a manufacturing method for the same.SOLUTION: In a carbon heater which is formed of a carbon base material having substantially 2D orthogonal anisotropy with respect to electric resistivity, and has a main heating portion which is substantially cylindrical or substantially disk-shaped, the direction of the central axis of the carbon heater is substantially coincident with the direction of the anisotropy of the electric resistivity in the carbon base material. Furthermore, in a carbon heater in which a main heating portion has rotational symmetry or spiral symmetry, the rotation axis direction or helical axis direction of the carbon-heater shape is substantially coincident with the anisotropic direction of electric resistivity in the carbon base material.SELECTED DRAWING: Figure 2
