The protective coating is a cured product of a coating agent containing a polyfunctional epoxy resin, a curing agent, an inorganic filler, and silicone rubber particles. The coating agent contains: silica as the inorganic filler at a content equal to or greater than 60% by weight and equal to or less than 90% by weight; and the silicone rubber particles at a content equal to or greater than 1% by weight and equal to or less than 15% by weight.
