PROBLEM TO BE SOLVED: To provide a silicone rubber composition for an extrusion molding by reducing die swell (swelling) in the extrusion molding. SOLUTION: This silicone rubber composition for the extrusion molding contains (a) 100 pts. mass organopolysiloxane expressed by an average compositional formula (1): R<SB>a</SB>SiO<SB>(4-a)/2</SB>[wherein, Rs are each the same or different kind non-substituted or substituted monovalent hydrocarbon group; and (a) is a positive number of 1.90-2.05], (b) 10-100 pts. mass reinforcing silica having at least 50 m<SP>2</SP>/g specific surface area, (c) 0.1-50 pts. mass isocyanurate compound having a specific structure and (d) a curing agent of an effective amount.
