The purpose is to provide a cold storage material composition to be used to store or transport goods in a low temperature range, the composition having little volume expansion during freezing, a cold storage material using the cold storage material composition, and a transport container provided with the cold storage material. Specifically, provided is a cold storage material composition characterized by containing a metal salt (A) having a eutectic point with water of -75 to -40°C and an inorganic salt (B) having a eutectic point with water of -30°C or higher and having a melting initiation temperature in the range of -75 to -40°C. |
