摘要：
Disclosed is a sealing material composition for a secondary battery, which is capable of providing a safe sealing layer that exhibits excellent adhesion in the sealing portion, while preventing leakage of the electrolyte solution. Specifically disclosed is a sealing material composition for a secondary battery, which is characterized by containing a diene rubber, a thermoplastic elastomer, carbon and an organic liquid material. The sealing material composition for a secondary battery is also characterized in that the number of coarse particles contained in 3 mL of the composition is 10 or less, said coarse particles having a maximum diameter of 10 μm or more.
