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.

A package for mounting an electronic element includes an insulating base including a frame section; an electrode pad disposed on an upper surface of the frame section; a first wall conductor disposed in an upper end part of an inner wall of the frame section so as to be electrically connected to the electrode pad; and a wiring conductor embedded within the frame section so as to be electrically connected to the first wall conductor. Consequently, the package for mounting an electronic element can be reduced in size, and is capable of suppressing electrical short-circuiting between the wiring conductor and an electronic element and of suppressing occurrence of a crack in the insulating base.
