The present invention provide a puncture instrument capable of administering (supplying) a drug solution. The puncture instrument includes a puncture tip section (); a first tubular body () connected to the puncture tip section () at the distal end; and an outer tubular body () at least partially covering the first tubular body (). The first tubular body () is formed to be rotatable around an axis along the longitudinal direction. The first tubular body () has an outer diameter smaller than an inner diameter of the outer tubular body (). A drug solution supply path () is provided on the outside of the first tubular body ().
