PROBLEM TO BE SOLVED: To provide a column and a column oven fit for efficiently and uniformly heating a fluid running in the column. SOLUTION: When an a.c. current is supplied to a coil 3 from a temperature control part 5, an a.c. magnetic field is generated along an axis direction, whereby an eddy current 6 as a heating current is generated to the center part 2a of each particle constituting a filler. As a result, the center part 2a itself heats by a Joule's heat. The whole of each particle 2, hence the column 1 including the entire filler is efficiently and uniformly heated.
