| description | An oil-well metal pipe according to the present disclosure has a high shear strength. An oil-well metal pipe according to the present disclosure includes a resin coating (100) on or above at least one of a pin contact surface (400) and a box contact surface (500). The resin coating (100) contains: a resin: 50.0 to 99.5 mass%, a wax: 0 to 10.0 mass%, a fluorine-based additive: 0 to 30.0 mass%, graphite: 0 to 10.0 mass%, a rust preventive pigment: 0 to 30.0 mass%, a coloring pigment: 0 to 10.0 mass%, a coupling agent: 0 to 10.0 mass%, and one type or two types selected from a group consisting of a magnesium silicate hydroxide powder: 1.5 to 50.0 mass% and TiO2: 0.5 to 30.0 mass%; and satisfies Formula (1).
