Abstract
An image pickup apparatus includes a semiconductor layer that constitutes a pixel circuit region and a peripheral circuit region. An element isolation portion is disposed in the pixel circuit region and the peripheral circuit region, defines an element portion of the semiconductor layer, and contains an insulator. The element isolation portion in the pixel circuit region has a hydrogen concentration 10 times or more higher than the hydrogen concentration of the element isolation portion in the peripheral circuit region.
