Abstract
There are provided an electronic element mounting board and an electronic device capable of suppressing transmission of incident light to an electronic device through a circumferential edge part of an opening of a board and thus of reducing a noise level in receiving an image. An electronic element mounting board includes an insulating substrate. The insulating substrate has an opening and a lower surface, and an electronic element is disposed on the lower surface so as to overlap the opening in a plan view. A circumferential edge part of the opening of the insulating substrate has a porosity lower than a porosity of a portion outside the circumferential edge part. Since it is possible to suppress transmission of incident light to the electronic element through the circumferential edge part, it is possible to reduce a noise level in receiving an image in the electronic element.
