PROBLEM TO BE SOLVED: To provide a siphon type rainwater draining device without increasing a cost and damaging external appearance of a house by efficiently draining a large quantity of rainwater due to siphon action during a heavy rain. SOLUTION: The siphon type rainwater draining device is provided with a siphon pipeline 1a on a bottom part 1e of an eaves gutter 1 over an entire length thereof, and a suction opening communicating with the siphon pipeline 1a from the inside of the eaves gutter 1. The upper end of a vertical siphon pipeline provided in a vertical direction along an outer wall 21 of the house is connected to the siphon pipeline of the eaves gutter 1. When the siphon pipeline 1a of an eaves gutter bottom part and the vertical siphon pipeline are satisfied with rainwater during the heavy rain, rainwater is sucked from the suction opening due to siphon action and flows down the siphon pipelines at a velocity several times of natural drop drainage, and the large quantity of rainwater is efficiently drained.
