PROBLEM TO BE SOLVED: To make the coagulation time of blood shorter than that of a blood specimen collection tube made of glass without requiring intricate production processes and to provide the blood specimen collection tube which allows the completion of blood-coagulation without unevenness and allows the conduction of a stable blood inspection free from individual differences. SOLUTION: This blood specimen collection tube is formed by enclosing a blood-coagulation accelerating agent prepd. by granulating inorg. matter, such as silica particles and materials such as materials like thrombine, derived from living things, having blood-coagulation activity into the tube. Further, the space of the blood specimen collection tube is bisected by a plastic film or the granular blood-coagulation accelerating agent or a serum separating agent is coated with water-soluble silicone in order to prevent the granular blood-coagulation accelerating agent from being adhered or captured by the serum separating agent and from degrading the coagulatability possessed by the blood-coagulation active material.
