PROBLEM TO BE SOLVED: To provide a drain trap reduced in a height dimension while securing drainage performance and enabling the extension width of a drain port to a wash place floor side to be suppressed. SOLUTION: The drain trap includes a seal water storage for storing seal water, a seal water tubular part which is provided so as to face the drain port of a waterproof floor pan and the bottom end of which intrudes into the seal water storage, and a drain part which is partitioned from the seal water storage by an overflow weir and which receives the drain flowing from the seal water storage over the overflow weir and feeds the drain to a drain passage. The drain trap receives the drain flowing from the drain port of the waterproof floor pan thereinto. The seal water tubular part is formed in an elongated hole shape in cross section.
