A tubular body (1) made of a fiber-reinforced plastic and used as a structural material of a vehicle includes corners (4) extending along an axis of the tubular body (1) on an outer circumferential surface thereof. The tubular body (1) is a tubular laminate that is formed by laminating a fabric layer (12) formed by laminating fabric materials and unidirectional material layers (11, 13). Each fabric material includes a fabric in which reinforcing fibers are woven and a plastic with which the fabric is impregnated. Each unidirectional material layer (11, 13) includes reinforcing fibers oriented in one direction and a plastic with which the reinforcing fibers are impregnated. The reinforcing fibers of each unidirectional material layer (11, 13) are oriented along the axis of the tubular laminate. The unidirectional material layers (11, 13) include an outer unidirectional material layer (13) laminated on an outer circumferential surface of the fabric layer (12), and an inner unidirectional material layer (11) laminated on an inner circumferential surface of the fabric layer.
