PROBLEM TO BE SOLVED: To provide a landslide detection device capable of detecting accurately and inexpensively a tilt state of the ground, and to detect beforehand a landslide, even if a time from ground tilt until falling is a very short time. SOLUTION: A tilt detection sensor 41 for detecting the tilt state of a pile part 2 piled into the ground has a constitution equipped with a lower side electrode body 42d comprising a circular cone-shaped electrode having a dented center part, an upper side electrode body 42u provided on a position facing to the lower side electrode body 42d, and a ball member 44 provided between the lower side electrode body 42d and the upper side electrode body 42u. A gap is provided with the upper side electrode body 42u on the center part, and a current is made to flow between the upper side electrode body 42u and the lower side electrode body 42d on the outer peripheral part, to thereby detect the tilt state. A rainwater detection device 6 for detecting rainwater in the ground is mounted on the pile part 2, and a report form is changed corresponding to the rainwater in the ground and the tilt state thereof.
