A radiation image capturing apparatus includes the following. A radiation detector includes a substrate in which a plurality of radiation detecting elements are arranged two-dimensionally. The plurality of radiation detecting elements receive radiation and generate charge in an amount according to an amount of received radiation. A reader reads the amount of charge generated in each of the plurality of radiation detecting elements as a signal value, and generates image data based on the signal value. A storage stores the image data generated by the reader. A hardware processor transmits the image data stored in the storage to an external terminal and an external device.
