An electrode component includes a ceramic substrate, two electrode layers formed on two opposite surfaces of the ceramic substrate, two pins respectively connected to the two electrode layers, and an insulating layer enclosing the ceramic substrate, the electrode layers and a portion of each pin. Each electrode layer is formed of two or more base metal materials or alloys thereof, and the concentrations of the base metal materials progressively vary across the electrode layer. Accordingly, the production cost is lowered, environmental pollution caused by evaporation and thermal dissolution of organic solvent can be prevented, risk of separable electrode interface at high-voltage discharge is mitigated, and the fabrication process of the electrode layer is shortened while maintaining bonding strength between the electrode layers and the ceramic substrate and solderability between the electrode layers and the pins. |
