Abstract

Provided is a method for manufacturing an interdental cleaning device () including a base portion () having a handle portion () and a core portion (); and a soft portion () having a cleaning soft portion (), a non-slip portion (), and connecting portions () extending from two sites of the non-slip portion () and being connected to the cleaning soft portion (). The method includes causing a second gate () of second molds () and () for molding the soft portion () to open at a position substantially equally distant from positions of two communicating openings () of a non-slip molding space () for molding the non-slip portion (), the two communicating openings () communicating with connecting portion molding spaces () for molding the connecting portions (); and charging the elastomeric material from the second gate () into a second molding space () for molding the soft portion () to fill the molding space ().
