Abstract
Provided is a dental handpiece which can prevent degradation in visibility of a surgical field. The anti-reflection layer 100 is formed on the top surface and the side surface of the head portion 241 of the lid member 24 close to the root canal of the tooth, to which the operator pays attention, and further on the outer surface of the second cylindrical member 12 (refer to FIG. 3). Therefore, the reflection of light of a dental lighting tool provided with the anti-reflection layer 100 is suppressed, and degradation in visibility of a surgical field can be avoided. In addition, visibility of stains such as proteins adhering to the lid member 24 and the second cylindrical member 12 is improved, and cleaning thereof is facilitated.
