Abstract
The present invention provides an electrostatic atomizer which can be inspected at low cost. The electrostatic atomizer includes: a PWM signal generating section (27) which generates a PWM signal for controlling a high voltage generating device (22); an identifying section (28) which identifies an on-time of a PWM signal during a certain time; and a reporting section (33) which causes a report to be sent out of the electrostatic atomizer in a case where the on-time identified by the identifying section (28) is larger than a certain value.
