Abstract

A seal member includes silicone rubber mixed with a polyrotaxane. The seal member includes the polyrotaxane in an amount of 3 to 10 parts by mass per 100 parts by mass of the silicone rubber. This configuration can allow molecules in the silicone rubber to slide on one another, so that the rubber material is easily deformed according to stress applied, such as insertion and removal of terminal metal pieces. Accordingly, scratch damage of the seal member can be reduced.
