Abstract
A sensor package substrate has through holes V1 and V2 at a position overlapping a sensor chip mounting area. The through hole V1 has a minimum inner diameter at a depth position D1, and the through hole V2 has a minimum inner diameter at a depth position D2 different from the depth position D1. Thus, since the plurality of through holes are formed at a position overlapping the sensor chip mounting area, the diameter of each of the through holes can be reduced. This makes foreign matters unlikely to enter through the through holes, and a reduction in the strength of the substrate is suppressed. In addition, since the depth position D1 and depth position D2 are located at different depth levels, it is possible to sufficiently maintain the strength of a part of the substrate that is positioned between the through holes V1 and V2.
