PROBLEM TO BE SOLVED: To provide a diffusing container in which operation from a sealing state of a container body before use to a usable state can be performed extremely simply compared with a conventional one, and an air introducing passage making the outside communicate with the inside of the container body can be formed certainly and easily after opening, and which is considerably convenient to use after being opened.SOLUTION: The container includes a cap D which closes the upper opening of the container body A having a liquid absorbing core C vertically fixed inside air-tightly and liquid-tightly and has an easy cut part 41a capable of being broken by pressing at the top part, and a supporting body E which is attached on the container body A in a threadly lowered manner and which is provided vertically with a needle-like connecting part 55 on the lower surface of a base plate 50 having diffusing plate F fitted and fixed to the upper surface, and which is provided with a liquid passage communicating between the connecting part 55 and the diffusing plate F, and a spacer G to prevent the supporting body E from being threadedly lowered, wherein the supporting body E is threadedly lowered after removing the spacer G and the connecting part 55 cutting and penetrating the easy cut part 41a thrusts the upper end of the liquid absorbing core C, and the liquid absorbing core C communicates with the volatilization plate F via the liquid passage.
