In conventional humidifiers, there was a risk that an upstream humidification filter and downstream humidification filter would come into contact, reducing vaporization efficiency. The present invention has: an upstream humidification filter (32) that is disposed upstream of an air flow generated by a blower fan; a downstream humidification filter (33) that is disposed downstream of the upstream humidification filter (32) such that a space (H) is formed between the downstream humidification filter (33) and the upstream humidification filter (32); a drive shaft (35 (shaft portion)) that passes through through-holes (32A, 33A) formed in the center portions of the upstream humidification filter (32) and downstream humidification filter (33); and a first spacer (43) that is disposed between an inner peripheral portion of the upstream humidification filter (32) and an inner peripheral portion of the downstream humidification filter (33). |
