Provided are a hose excelling in a lightweight property and in fatigue fracture resistance, a method for manufacturing the hose, and a hydraulic pump. The hose includes a tube, an interior of the tube being hollow, continuous carbon fibers and/or continuous glass fibers wound around an outer circumference of the tube, and a thermosetting resin present external to the tube. The thermosetting resin has an elastic modulus from 0.5 to 10 MPa, and the continuous carbon fibers and/or continuous glass fibers are impregnated with at least a part of the thermosetting resin. The elastic modulus of the thermosetting resin is a numeric value determined by: heating the thermosetting resin for 2 hours at a curing temperature of the thermosetting resin; then subjecting the thermosetting resin to thermoregulation for two weeks under a condition of a temperature of 23° C. and a relative humidity of 55%; and then performing a measurement in accordance with JIS K7161:2019.
