Abstract
A cutting tool comprises: a plate member which is provided, at a leading end thereof, edge parts; a support member which supports the plate member so as to cause the edge parts to be projected; and a coolant supply part which has an ejection port and which ejects, from the ejection port, fluid that cools the edge parts. The support member has a non-contact surface which forms a gap with respect to an outer side surface of the plate member. The gap is opened toward a side where the edge parts are provided. The ejection port is arranged in the gap, and the ejection port ejects the fluid toward the plate member.
