## Abstract

In an electric taste adjustment device that adjusts taste using electrical signals when eating or drinking, electrodes must be attached in order to apply electrical signals. An electric taste adjustment device is provided to eliminate this hassle. The electric taste adjustment device 1 is attached to a food container, and when the food container is taken into the mouth, the electrodes 1 and 2 connected to the electric taste adjustment device 1 contact an upper mandible and a mandibular base, respectively, to apply an electric signal. This makes it easy to attach electrodes for taste adjustment.
