An excrement detection sensor in which two pairs of conductors 1,2 and 3,4 are formed between a carrier body 6 and a coating body 7 both having water-proof property and insulating property, wherein the cover body is formed with an urine introduction port 8 correlating the paired conductors and with a faeces introduction port 9 correlating the other paired conductors, and when urine enters into the urine introduction ports, the one pair of the conductors are short-circuited and when faeces enters into the faeces introduction ports, the other one pair of the conductors are short-circuited, whereby the urination and the evacuation can be distinctively detected.排列而延伸的至少二對導線1、2,同時包夾於具防水性與絕緣性的載持體6與被覆體7之間,在被覆體中形成連結於一對導線之間的尿液導入孔8,並形成連結於另一對導線之間的糞便導入孔9,尿液進入尿液導入孔內時,一對導線之間發生短路,糞便進入糞便導入孔內時,另一對導線之間發生短路。藉此可區分排尿或排便而檢測之。1、2、3、4...導線1a、2a、3a、4a...端子部3b、4b...擴充部5...排泄物檢測感應器6...載持體6a...連接部7...被覆體8...尿液導入孔9...糞便導入孔12...定位孔13...缺口14...高電阻導線15...尿通過孔30...記號
