PROBLEM TO BE SOLVED: To provide a platform edge structure that has high resistance to deformation caused by force working in a perpendicular direction and inhibits occurrence of breakage caused by contact with a train.SOLUTION: A platform edge structure includes: a base body 2 installed on a sidewall of a platform; a plurality of comb teeth sections 3 extended in a horizontal direction from the base body 2; and a top plate 4 covered while forming intervals formed at the plurality of comb teeth sections 3 extended from the base body 2. The plurality of comb teeth sections 3 includes a plurality of long first comb teeth 3a and a plurality of short second comb teeth 3b in the perpendicular direction. The first comb teeth 3a and the second comb teeth 3b are alternately arranged and a top end of the first comb teeth 3a is disposed to project from a top end of the second comb teeth 3b. The top plate 4 includes a recess 7 in which the top end of the first comb teeth 3a coincides with the bottom face and a protrusion 8 in which the top end of the second comb teeth 3b coincides with.
