An interdental brush comprises bristles (11), a wire (12) with which the bristles (11) are twisted, and a handle (13) to which the wire is attached. The handle (13) is composed of a main body (21) and a sub-body (22). The main body (21) is provided with a longitudinal hole (41) into which a base part of the wire (12) is inserted, and a lateral hole (43) intersecting the longitudinal hole (41). A coming-off preventing bent portion (51) is formed at the base part of the wire (12) so as to be exposed to the lateral hole (43). The sub-body (22) is provided with an engagement portion (52) filling the lateral hole (43) so as to surround a periphery of the bent portion (51). |
