1. A hose comprising: 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 having an elastic modulus from 0.5 to 10 MPa, and
the continuous carbon fibers and/or continuous glass fibers being impregnated with at least a part of the thermosetting resin; wherein
an 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; subsequently 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; and
thermoplastic resin fibers wound around an outer circumference of the continuous carbon fibers and/or continuous glass fibers.
