PROBLEM TO BE SOLVED: To provide a heat responding steam trap in which first and second diaphragms can open first and second outlet channels, respectively. SOLUTION: The trap includes: forming an inlet 4, a valve chamber 3 communicating with the inlet 4, and the outlet 5 communicating with the valve chamber 3 via the first outlet channel 8 and the second outlet channel 10 by valve casings 1, 2; sealing an expandable medium 16 in the inside space between the first diaphragm 14 and the second diaphragm 15; arranging the stopper member 21 regulating the displacement not less than predetermined displacement in the direction opening the valves of the first diaphragm 14 opening the first outlet channel 8 and the second diaphragm 15 opening the second outlet channel 10 between the first outlet channel 8 and the second outlet channel 10 of the temperature control element 12 arranged in the inside space between the first diaphragm 14 and the second diaphragm 15; and opening and closing the first outlet channel 8 and the second outlet channel 10 by the displacement of the first diaphragm 14 and the second diaphragm 15 by the expansion and contraction of the expandable medium 16.
