PROBLEM TO BE SOLVED: To provide a vibration stimulus to a user's body by forming a space where vibration components due to rhythm of a driving device and vibration components emitted from an externally attached vibration device intersect each other and which is characterized by vibration characteristics. Provided are a space-forming device and a method of applying a vibrational stimulus to the body, which can be applied or modified with substances such as water and salts. SOLUTION: A housing portion 21 in which a driving device is housed in a hollow portion, a lid body 22 that covers the housing portion 21 and pulsates in a vertical direction by driving the driving device, and an externally attached vibration device 23 are provided. However, the vibration device is arranged such that the vibration component due to the vertical rhythm of the lid 22 and the vibration component from the externally attached vibration device intersect in the space above the lid 22.
