1. An imaging apparatus for an endoscope comprising:
a coupler configured to
hold an endoscope for capturing an image of a subject, and
emit the image of the subject;
an exterior casing connected to the coupler and extending along a first axis crossing an optical axis of the endoscope, the exterior casing having outer dimensions in a direction along the first axis greater than outer dimensions in a direction along the optical axis of the endoscope;
an optical system configured to guide light of the image of the subject; and
an image sensor configured to capture the image of the subject through the optical system, wherein
the exterior casing includes
a first exterior part including
a first side wall and a second side wall crossing the optical axis of the endoscope,
a first opening in the first side wall,
a second opening in the second side wall which is further away from the coupler than the first side wall, and
a third opening in a third side wall crossing the first axis,
a second exterior part connected to the first exterior part to seal the second opening of the first exterior part, and
a connector part connected to the first exterior part to seal the third opening of the first exterior part and is configured to connect to a cable for transmitting an image signal output from image sensor, and
the optical system and the image sensor are housed, in the exterior casing, side by side on the optical axis of the endoscope such that the light of the image of the subject guided by the optical system is captured by the image sensor.
