PROBLEM TO BE SOLVED: To provide a drain outlet structure preventing a mineral surfaced increaser from dust getting therein, facilitating the removal/collection of the dust and imposing no forced stress also on force from above. SOLUTION: The drain outlet structure comprises the mineral surfaced increaser 1 mounting an interlocking rod 12 for fitting a roof drain downward of the drain outlet 8 and the roof drain 2 cutting and forming an L-shaped guide groove 15 in the bottom of the body section 13 and having a water passing mechanism on the ceiling section 14. When the roof drain 2 is fitted in the mineral surfaced increaser 1 through the interlocking rod 12, the lower end of the roof drain 2 is supported by the flat section 11 of the mineral surfaced increaser 1.
