To enable information on urination to be constantly measured with a high degree of accuracy by preventing an influence from being exerted by a pressure fluctuation caused in sewage piping by having water discharged into the sewage piping from other instruments, while maintaining the inevitability that discharged urine is sanitarily treated, when the information on a urination state such as a urine volume and a urine flow rate is measured by measuring a change of a stored water level in a toilet for generally performing excretion.
This closet bowl is characterized in that a water-passage opening and closing means is arranged in a drainage socket. Thus, the pressure fluctuation, which is caused in the sewage piping by having the water discharged into the sewage piping from the other instruments, prevents the change of the stored water level, so that the information on the urination can be constantly measured with a high degree of accuracy.
