A coating film transfer tool in which a rotational torque with the least variability may be generated without being affected by a surface state of a resilient body may include: a paying-out core having a coating film transfer tape wound thereon; and a rewinding core that rewinds the coating film transfer tape after use. The paying-out core and the rewinding core are interlocked via a power transmission mechanism in a case. The transmission mechanism generates a rotational torque by a frictional force on a sliding surface between components, by using a restoring force of a resilient body. The resilient body is configured to rotate integrally with a component A that comes into contact with one end of the resilient body and a component B that comes into contact with the other end.
