Abstract: An organ container includes a pouch-shaped body. The body has an opening and is capable of storing an organ that is inserted from the opening into an inner space. The body is formed of a styrene elastomer. The body has inner and outer surfaces each having a uneven shape. This structure suppresses a temperature rise in the organ stored in the body and reduces damage to the organ when some sort of impacts is applied to the organ. Moreover, the uneven shape of the inner surface of the body allows holding of a low-temperature preservation solution and thereby improves insulation effectiveness of the organ. The uneven shape of the outer surface of the body facilitates the surgeon's handling of the organ container and thereby improves workability.
