On the relationship between the waveguide shape and the vibration modes present in the waveguide, we solve a modal continuity equation. In the process, a virtual waveguide is assumed and solved. A virtual waveguide is defined based on numerical data calculated from the modal continuous equation. In addition, the existence of geometric mode distribution of vibration modes is defined, and it is confirmed that the virtual waveguides defined for each are the same. From the vibration analysis results by the finite element method, a mode continuous equation was created assuming the vibration mode, and it is consistent with the assumed vibration mode. In the actual mode, the assumed virtual waveguide was not realized, and it was confirmed that it was used as a tool for analyzing the waveguide
