Silicone rubber composition for waterproofing, silicone rubber molded body for waterproofing, and wire harness

A wire harness comprising a waterproofing part, wherein

• a silicone rubber molded body for waterproofing is disposed in the waterproofing part;
• the silicone rubber molded body for waterproofing configured by a cured product of a silicone rubber composition for waterproofing, the silicone rubber composition for waterproofing containing:
• a vinyl group-containing compound, the vinyl group-containing compound being a monofunctional vinyl group-containing compound, and
• a thermosetting silicone rubber,
• the silicone rubber composition having a Shore A hardness of not more than 25 after being cured and a breaking strength of at least 7.5 MPa but not more than 10.5 MPa after being cured, wherein
• a molar ratio (a:b) between a vinyl group (a) of the vinyl group-containing compound and a hydrosilyl group (b) in the thermosetting silicone rubber is in a range between 10:1 and 0.2:1.
