Zusammenfassung:	Provided are a composition for the purpose of obtaining a threaded pipe joint having excellent anti-galling properties and excellent high torque properties, and a threaded pipe joint provided with a lubricant coating layer formed from the composition, and having excellent anti-galling properties and excellent high torque properties. This composition is for the purpose of forming a lubricant coating layer (21) on a threaded pipe joint, and contains polyisobutylene, metallic soap, wax, and a basic aromatic organic acid metal salt. This threaded pipe joint comprises: a pin (3) having a pin-side contact surface (34) containing a pin-side threaded section; a box (4) having a box-side contact surface (44) containing a box-side threaded section; and a lubricant coating layer (21) comprising the composition and serving as the outermost surface layer on the pin-side contact surface (34) and/or the box-side contact surface (44).
