PROBLEM TO BE SOLVED: To provide an excrement detection sensor for detecting urine and feces discriminably. SOLUTION: At least two pairs of lead wires 1, 2 extending in parallel are inserted between a carrier 6 and a covering body 7 having water proofing property and insulating property together. In the covering body, a urine introduction hole 8 correlating one pair of lead wires with each other is formed, and a feces introduction hole 9 correlating the other pair of lead wires with each other is formed, and when urine enters the urine introduction hole, the one pair of lead wires becomes short-circuited, and when feces enter the feces introduction hole, the other pair of lead wires becomes short-circuited. Hereby, urination and defecation can be detected discriminably. COPYRIGHT: (C)2008,JPO&INPIT
