Abstract: The present invention is intended to prevent lifetime degradation of a conductor tube by reducing heat deterioration at output ports of the conductor tube. A superheated steam generator generates superheated steam by heating steam flowing through a spirally wound cylindrical conductor tube. The conductor tube is axially short-circuited and subjected to induction heating by a magnetic flux generation mechanism disposed on one or both of inner and outer sides of the conductor tube. Output ports of the conductor tube are disposed at axial midportions of the conductor tube.

Abstract: The present invention intends to suppress energy consumption despite making it possible to generate superheated steam in a short period of time. Specifically, the present invention includes: a steam generating part that generates steam; a superheated steam generating part that generates superheated steam; and an on/off valve that switches the supply of the steam to the superheated steam generating part or the stop of the supply, wherein the on/off valve switches the supply of the steam or the stop of the supply, and thereby switching is performed between a waiting state that is a state where the steam generating part generates the steam and a state where the supply of the steam is stopped, and a supply state where the steam is supplied to the superheated steam generating part.
