PROBLEM TO BE SOLVED: To provide a steam trap hardly clogged at all by changing a complete flow passage of condensate, by increasing the combination number of orifices and valve chests in a limited space. SOLUTION: An orifice body 20 is formed by respectively juxtaposing a plurality of blocks 21-23 in the series direction in a state of bringing mutual longitudinal end surfaces into close contact with each other. The plurality of blocks 21-23 have an inside flow passage 20a for turning to the outlet side after introducing fluid in one direction and its inverse direction from the inlet 24 side by circulating the fluid by mutually communicating between the respective blocks 21-23. A combination of orifice flow passages 31-35 of a small diameter cross section and the valve chests 41-44 expanding to its outlet side, is successively formed in a plurality of places along the inside flow passage 20a.
