摘要

PROBLEM TO BE SOLVED: To provide a brush body and toothbrush that have a structure allowing for current to easily flow from conductive bristles to oral tissues or enhance ionization of electrolytic medicinal components.SOLUTION: The brush body 10 includes a mixed bristle bundle 70 arranged on an anchoring surface 13 and including conductive bristles 30 having conductive properties and insulative bristles 40 having insulation properties. A reference plane is set on the anchoring surface 13. The conductive bristles 30 have a height from the reference plane, and the insulative bristles 40 have a height from the reference plane that differs from the height of the conductive bristles.
