The present invention relates to a diaper with a fecal detection function, and more particularly, it is harmless to the human body and does not cause skin troubles, and can be manufactured at a low cost and can be repeatedly reused because the wearing comfort is improved. The present invention relates to a diaper having a toilet detection function capable of reducing contamination, wearing it conveniently, not causing inconvenience to the wearer, and improving the detection efficiency of the toilet. In the diaper having a fecal detection function according to the present invention is a diaper having a diaper body and a diaper body having a fecal detection device installed on the diaper body to detect the feces, the diaper body is a liquid permeable top sheet, liquid An impermeable back sheet, an absorbent body disposed between the liquid permeable top sheet and the liquid impermeable back sheet, wherein the sensing device accommodating space portion is formed in the liquid impermeable back sheet for accommodating the stool sensing device. do. The sensing device accommodating space part is integrally connected with the isolation sheet part so as to form an isolation sheet part formed in the liquid impermeable back sheet so as to contact the absorber, and an accommodating space therein is formed therein. And a sheet connecting portion, wherein the separator sheet portion and the sheet connecting portion are formed of a liquid impermeable material. According to this, the sensing line is not integrally embedded in the diaper body disposed of after use, and the toilet can be repeatedly reused by inserting and separating the toilet sensor into the sensing unit accommodating space, thereby simplifying the manufacturing process of the diaper. Eliminating the need to embed the sensing wires can reduce the manufacturing cost of the diaper and reduce the cost burden for the consumer. In addition, the diaper having a fecal detection function according to the present invention h
