Abstract:
1. A heat curable silicone rubber composition, comprising: (A) 100 parts by mass of an alkenyl group-containing polyorganosiloxane expressed by a following general formula (1), having an average degree of polymerization of 500 to 20,000, and having two or more alkenyl groups in a molecule, where R 1 represents an unsubstituted or substituted monovalent hydrocarbon group containing no aliphatic unsaturated group, R 2 represents an alkenyl group, R 3 represents a monovalent group indicating R 1 or R 2 , or hydroxyl group independently, n and m represent the total numbers of each recurring units obtained by random polymerization or block polymerization, and n+m+2 obtained by adding 2 that is the number of terminal groups to n and m represents an average degree of polymerization; (B) 5 to 100 parts by mass of a filler; (C) an effective amount of an organic peroxide; and (D) 0.06 to 15 parts by mass of a hydrous oxide selected from the group consisting of a hydrous cerium oxide and a hydrous zirconium oxide each having one absorption band in 3300 to 3500 cm
