Abstract: An object is to provide a urinal which prevents offensive odors, reduces the consumption of urinal cleaning water and prevents clogging of the urinal drain pipe line. The urinal of the present invention includes a human body sensor (7), a control unit (11), a mechanism to generate a gas with high detergency (14), a gas flow line (La) in which generated gas with high detergency flows, and a cleaning water supply line (Lw) in which cleaning water flows, and the gas flow line (La) and the cleaning water supply line (Lw) converge to mix the gas with high detergency with the cleaning water, and a cleaning fluid line (Lc) formed by confluence of the gas flow line (La) and the cleaning water supply line (Lc) is communicated with a cleaning fluid ejection hole (5) on a urinal upper edge (1a).
