1. A porous carbon,
wherein the porous carbon has an ID/IG of 2.0 or more in a Raman spectrum measured by Raman spectroscopy with respect to the porous carbon, wherein the IG is an accumulated intensity of a peak for G band around 1590 cm−1, and the ID is an accumulated intensity of a peak for D band around 1350 cm−1,
wherein the porous carbon has pores having a size of 200 nm or more and less than 1 μm, and
wherein the porous carbon is porous carbon for a varistor element.
