Abstract
Abstract A solid state image pickup mounting structure which is used to mount a low pass filter onto the upper surface of a solid state image pickup element and fix them to a reference plate. The mounting structure includes a low pass filter holder formed of an elastic material and having first and second frame portions, and fastening means for fastening and fixing the low pass filter holder through the solid state image pickup element onto the reference plate. According to the mounting structure, the low pass filter is press fitted into the first frame portion of the low pass filter holder and the solid state image pickup element is mounted to the second frame portion in a manner similar to press fitting to thereby form them into a unit with the low pass filter on board the front surface of the solid state image pickup element, and the integrally formed members are then fastened and fixed onto the reference plate by the fastening means.
