Abstract
A test container includes a container main body including a first-accommodation-portion, a second-accommodation-portion, and a third-accommodation-portion each accommodating a liquid and internally provided, a first flow path connecting the first-accommodation-portion and the second-accommodation-portion to each other at respective upper end positions thereof and internally provided, and a second flow path connecting the second-accommodation-portion and the third-accommodation-portion to each other at respective upper end positions thereof and internally provided, in which at least a portion forming an upper wall surface of the second-accommodation-portion has flexibility to be deformable inwards of the second-accommodation-portion; and a liquid return prevention structure which prevents a backflow of the liquid to the first-accommodation-portion, when the liquid accommodated in the second-accommodation-portion is fed to the third-accommodation-portion via the second flow path due to deformation of the portion forming the upper wall surface of the second-accommodation-portion inwards of the second-accommodation-portion.
