PROBLEM TO BE SOLVED: To provide a boundary block between a sidewalk and a roadway capable of reducing clearance generated between opposed surfaces when disposing a plurality of the boundary blocks between the sidewalk and the roadway in a curve section of a road, and a boundary structure between the sidewalk and the roadway constituted of the plurality of boundary blocks between the sidewalk and the roadway.SOLUTION: A boundary block 100 between a sidewalk and a roadway includes: a boundary section (projection section) 12 indicating a boundary between the sidewalk and the roadway; a roadway side apron section 14a which continuously projects from each of a side surface facing the roadway side of the boundary section and a side surface facing the sidewalk side and is provided along the roadway; and a sidewalk side apron section 14b provided along the sidewalk. A length (an edge side 15b of the sidewalk side apron section 14b) along the sidewalk of the block is formed to be shorter than a length (an edge side 15a of the roadway side apron section 14a) along the roadway of the block.SELECTED DRAWING: Figure 4 【課題】道路の曲線部の歩道と車道との間に複数配設する際に対向する面間に生じる隙間を小さくすることを可能とした歩車道境界ブロック及びこれら複数個の歩車道境界ブロックにて構成される歩車道境界構造体を提供する。【解決手段】歩道と車道の境界を示す境界部（突起部）１２と、境界部の車道側に面した側面と歩道側に面した側面からそれぞれ連続して突出し、車道に沿って設けられた車道側エプロン部１４ａと、歩道に沿って設けられた歩道側エプロン部１４ｂと、を含んで構成される歩車道境界ブロック１００であって、当該ブロックの歩道に沿った長さ（歩道側エプロン部１４ｂの縁辺１５ｂ）が、当該ブロックの車道に沿った長さ（車道側エプロン部１４ａの縁辺１５ａ）に比して短く形成した。【選択図】図４
