Abstract: A container for a specimen is disclosed. According to the present invention, in the container for a specimen, a specimen is stored in a first container, and a fixative is sealed and stored by a second container and a barrier film. In addition, a fixative of the second container flows into the first container in a state in which the first container and the second container are coupled to each other by means of a connection member, and thus the fixative does not leak to the outside when the fixative flows into the first container in which the specimen has been placed. Therefore, fixative leakage is relatively inhibited compared with that of a conventional specimen container in which a fixative leaks to the outside, when a specimen is put into a container main body or taken out from the container main body, and thus the present invention can have effects of enabling damage to a worker's health to be prevented as much as possible and environmental pollution to be prevented as much as possible.
