Abstract
In a steam cooker, a tray-shaped case () of a steam temperature-raising device () has a recessed part () into which steam from a steam generator flows through steam supply ports (A,B,C) provided in a first sidewall (). The recessed part () has a planar shape roughly symmetrical with respect to a center line (L) of a steam flow entering through the steam supply ports (A,B, andC). First and second steam superheaters () are placed in the recessed part () of the tray-shaped case () so as to be symmetrical with respect to the center line (L). A spiral heat radiation fin () having a fin pitch of 10 mm or less is wound around the first steam superheater (). The tray-shaped case () is placed on a ceiling panel of a heating chamber and at steam outlets with an opening of the recessed part () directed downward.
