Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an earth module suitable for increasing both of the durability and electrical conductivity, and a method for manufacturing such an earth module.SOLUTION: An earth module comprises: a resistor 10 extending along a longitudinal direction; and a conducting core rod 20 disposed in a center portion of an axial transverse section of the resistor 10. The resistor 10 is arranged by mixing up 70-85 wt.% of graphite, 15-30 wt.% of coal-tar pitch having a particle size of about 60 mesh, and 0.5-0.7 wt.% of copper chloride having a particle size of about 325 mesh to total 100 wt.%.
