A guidewire includes a shaft, an outer coil wound around a distal end portion of the shaft, and an inner coil provided within the outer coil. The outer coil is formed by winding a plurality of stranded wires in a spiral manner, each of the stranded wires being formed of a plurality of elemental wires twisted together, and the direction of winding of the outer coil is opposite to the direction of winding of the inner coil.
