PROBLEM TO BE SOLVED: To obtain a lighting surge protector capable of eliminating a potential difference produced between the power supply circuit and communication circuit of a connected apparatus by a lighting surge and hence surely protecting the connected apparatus with superior safety and reliability. SOLUTION: A lighting surge into power lines 11a and 11b is suppressed by a lighting protective device 13, and a lightning surge into communication lines 12a and 12b is suppressed by a lightning surge protective device 15. Particularly, by grounding the lightning protective device 13 and the lightning protective device 15 in common, a potential difference between the power lines 11a and 11b and the communication lines 12a and 12b by the lightning surge can be prevented. |
