Abstract
An electrical toothbrush includes an electrical toothbrush main body including a drive source of a brush; an orientation sensor configured to detect an orientation of the electrical toothbrush main body; and a controller configured to switch an operation mode of the electrical toothbrush according to a result of comparing an orientation value, which is a value calculated from an output of the orientation sensor, and a threshold value set in advance. A threshold value used for switching determination from an operation mode to an operation mode, and a threshold value used for switching determination from the operation mode to the operation mode are set to different values.
