PROBLEM TO BE SOLVED: To provide a plant raising material support body which comprises: porous supporting board part for supporting a plant raising material, which is capable of downward water permeation and vertical ventilation, on an upper side thereof and a large number of support posts which are fixed below the supporting board part and support the supporting board part, in which the support body is capable of increasing fixability to a mounting surface part in the state of being mounted on the mounting surface part, and to provide a plant raising material support structure using the plant raising material support body, and a method of manufacturing a plant raising material support structure.SOLUTION: A plant raising material support body 10 comprises a large number of support posts 30, 32 which are fixed below a porous supporting board part 20 for supporting a plant raising material 60, which is capable of downward water permeation and vertical ventilation, on an upper side thereof, and support the supporting board part 20. A large number of support posts 30 are positioned in a predetermined section 25 in a planar view, and the support posts 30 are connected with each other via a connection plate part 40 of a flat bottom surface mountable on a mounting surface part by fixing lower end parts of a plurality of adjacent support posts 30 to the connection plate part 40.COPYRIGHT: (C)2016,JPO&INPIT【課題】 植物生育材を上側に支持するための下方透水及び上下通気可能な多孔状の支持盤部と、その支持盤部の下側に固定されて支持盤部を支持する多数の支柱部を備えてなり、被載置面部上に載置した状態においてその被載置面部に対する固定性を高めることができる植物生育材支持体、その植物生育材支持体を用いた植物生育材支持構造及び植物生育材支持構造の製法の提供。【解決手段】 植物生育材60を上側に支持するための下方透水及び上下通気可能な多孔状の支持盤部20の下側に固定されて支持盤部20を支持する多数の支柱部30・32を備えた植物生育材支持体10。平面視における所定区域25内に多数の支柱部30が位置し、隣接する複数の支柱部30の下端部を、被載置面部上に載置され得る底面水平状の連結板部40に固定されることにより、支柱部30同士を連結板部40を介して連結する。【選択図】 図11
