In a capsule endoscope that functions as one example of a body insertable apparatus, a first imaging mechanism, a second imaging mechanism, a data generator, and a timing controller are provided on a same imaging board. The first imaging mechanism and the second imaging mechanism are arranged inside an outer casing member that determines an outer shape of the capsule endoscope. The data generator generates image data based on electric signals obtained by the imaging mechanisms. The timing controller controls driving timings of the first imaging mechanism, the second imaging mechanism, and the data generator. Since the aforementioned elements are formed on the same board, increase in number of the board can be suppressed.
