There is provided a urination control device capable of autonomous urination by adjusting the intravesical pressure with the abdominal pressure in starting the urination to prevent urinary incontinence, variously designing the intravesical pressure in opening and closing and gaining the stability and accuracy of the operation while ensuring the control of urination by secure closing and opening operation, and preventing infection and contamination by employing a simple structure and safe constituent materials and being applied to both men and women while improving QOL of the patients. The urination control device of the invention comprises a conduit to be inserted into the urethra, an upstream restraint member located upstream of the conduit and having a through hole, a control member located on the downstream side from the upstream restraint member in the conduit, and a downstream restraint member located on the downstream side from the control member in the conduit, wherein the upper restraint member and control member attract each other with magnetic force, the control member is brought in contact with the opening portion of the through hole in the upstream restraint member at least in the state exerting no fluid pressure on the upstream side so as to block passage of fluid through the upstream restraint member and admit the passage of fluid through the downstream restraint member in the state engaged with the control member.
