To provide a molding structure which has high water absorption property and hydrophilic property, and is excellent in droplet discharge property and antifogging property.SOLUTION: A molding structure has a base material, and at least one first groove formed by connecting a plurality of groove elements in a line in a first direction on the surface of the base material. Each of the plurality of groove elements has a first region and a second region connected in a first direction of the first region, when a cross section in a surface vertical to the first direction, which is a boundary surface between the second region of the groove elements and the first region of the groove element adjacent to the groove element, is defined as a first opening surface, and a cross section in the surface vertical to the first direction, which is a boundary surface between the first region and the second region of the groove element, is defined as a second opening surface, the second region has a groove width and a groove depth reduced toward the first opening surface from the second opening surface, the first region has a groove cross section having such a size as to be larger than the second opening surface on the boundary surface and include the second opening surface, has a constant groove cross section and extends in the first direction.SELECTED DRAWING: Figure 2B 【課題】高い吸水性及び親水性を有し、液滴排出性及び防曇性に優れた成形構造体を提供する。【解決手段】基材と、基材の表面に複数の溝要素を第１の方向に沿って一列に連結してなる少なくとも１つの第１の溝と、を有している。複数の溝要素の各々は、第１領域と、第１領域の第１の方向に接続された第２領域とを有し、溝要素の第２領域と溝要素に隣接する溝要素の第１領域との境界面であり、第１の方向に垂直な面における断面を第１開口面とし、溝要素の第１領域と第２領域との境界面であり、第１の方向に垂直な面における断面を第２開口面としたとき、第２領域は、第２開口面から第１開口面に向かうに従って溝幅及び溝深さが減少し、第１領域は、境界面において第２開口面より大きく第２開口面を包含する大きさの溝断面を有し、第１の方向に一定の溝断面を有して伸長している成形構造体。【選択図】図２Ｂ
