Image capturing device and image capturing module thereof

An image capturing module, comprising:

• a holder having a first surface, a second surface, two through holes and two positioning sections, the first surface and the second surface being opposite to each other, the two through holes extending from the first surface to the second surface, the two positioning sections located on the second surface, and the two positioning sections respectively surrounding the two through holes;
• two camera lenses respectively disposed in the two through holes;
• and
• two image assemblies, each of the two image assemblies comprising a circuit board and an image sensor, each of the two image sensors having an image surface, the two image sensors respectively electrically connected to the two circuit boards, the two positioning sections respectively abutted against sides of the two image sensors so as to position the two image sensors, thereby respectively locating two centers of the two image surfaces on two central axes of the two camera lenses.
