Abstract: A collecting implement includes a cylindrical body portion having a stretchability; and a hollow portion formed in the body portion, wherein the hollow portion includes an inlet portion which is formed such that one end side of the body portion is open and through which a material is introduced; and a collecting portion which is formed continuously from the inlet portion and contains the material. In the collecting portion, a predetermined part is more stretchable than a part of the collecting portion other than the predetermined part so that the predetermined part can bulge toward an outer side of the body portion when the material introduced from the inlet portion is contained.
