摘要： PROBLEM TO BE SOLVED: To provide an electrostatic countermeasure component suitable for a high-frequency circuit which can suppress voltage to be applied to an electric circuit of an apparatus by making electrostatic pulses bypass, and also to provide a method of manufacturing the same. SOLUTION: The electrostatic countermeasure component is mainly composed of a ceramic sintered body having at least a pair of external electrodes. Then, a varistor 16 and an inductor 15 are formed in the ceramic sintered body. An internal electrode 14 of the varistor 16 and an inductor conductor 11 of the inductor 15 are electrically connected to the external electrodes. The varistor 16 and the inductor 15 are electrically connected in parallel to each other to be integrated. When the static electricity control component is installed between a signal line of an apparatus circuit and the ground, electrostatic pulses are made to bypass the part to the ground due to the existence of the inductor, and at the same time, high-frequency components which could not be removed by the inductor can be absorbed by the varistor, resulting in obtaining the electrostatic countermeasure component with a superior capability to suppress voltage to be applied to the electric circuit of the apparatus.
