Publication number: 20240142642Abstract: A radiation imaging apparatus includes a radiation detection sensor, a support base, a bonding member, and a wiring member. The radiation detection sensor is configured to detect radiation and is formed using a flexible substrate. The support base supports radiation detection sensor. The bonding member bonds a first region of the radiation detection sensor to the support base. The first region is located in a central portion of the radiation detection sensor. The wiring member is connected to a predetermined edge portion of the radiation detection sensor. A second region is a region of the radiation detection sensor that includes the predetermined edge portion, and the second region opposes the support base but is not adhered to the support base.Type: ApplicationFiled: October 24, 2023Publication date: May 2, 2024Inventors: AKIRA KIDA, TAKAAKI GONDA, TOMOHIRO HOSHINA, KAITO MIYASHITA
