An image sensor package includes a substrate, an image sensor chip disposed on the substrate, and an external force absorbing layer disposed between the substrate and the image sensor chip and having a first surface and a second surface opposite to the first surface. The image sensor package further includes an adhesive layer configured to bond the second surface of the external force absorbing layer to the substrate. The adhesive layer has a first modulus, and the external force absorbing layer has a second modulus different from the first modulus.
