Abstract
A silicone rubber composition for waterproofing which is capable of maintaining waterproofing performance even if flexing and bending occur; a silicone rubber molded body for waterproofing; and a wire harness. This silicone rubber composition for waterproofing includes a thermosetting silicone rubber, has a Shore A hardness of not more than 25 after being cured, and has breaking strength of at least 5.0 MPa after being cured. The silicone rubber composition for waterproofing is used in a waterproofing part of a wire harness. It is preferable that a vinyl group-containing compound be included in addition to the thermosetting silicone rubber. A vinyl group-containing compound may be a monofunctional vinyl group-containing compound.
