PROBLEM TO BE SOLVED: To provide a grid for capturing an X-ray image, which has reduced variations in X-ray transmission and prevents occurrence of sticking phenomenon to collapse an X-ray transmission part during manufacturing.SOLUTION: When grooves 24 to form an X-ray absorption part 19 are formed on an X-ray transmissive base plate 21, a bridge part 28 of a transmission part which serves as a link between X-ray transmission parts 26 across the groove 24 and a connecting groove 30 which serves as a link between the grooves 24 are formed. The connecting groove 30 improves flow of plating solution in the grooves 24 to prevent the X-ray transmission part 26 from collapsing due to uneven plating deposition. An X-ray absorbing material 25 filled in the connecting groove 30 functions as a bridge part 29 of an absorption part to reinforce the X-ray absorption part 19.COPYRIGHT: (C)2012,JPO&INPIT【課題】グリッドのX線透過率のバラツキを小さくするとともに、X線画像撮影用グリッドの製造時に、X線透過部が倒れてしまうスティッキング現象の発生を防止する。【解決手段】X線透過性基板21に、X線吸収部19が形成される溝24を形成する際に、溝24を隔てているX線透過部26の間を連結する透過部用ブリッジ部28と、各溝24の間を連結する連結用溝30を形成する。連結用溝30は、溝24内のメッキ液の流れを改善し、メッキの不均一成長によってX線透過部26が倒れるのを防止する。連結用溝30に充填されたX線吸収材25は、X線吸収部19を補強する吸収部用ブリッジ部29として機能する。【選択図】図3
