Abstract
A biosensor for detecting the toxicity of a sample includes a solid-state area image pickup element, a culture container positioned on an upper surface of a light-receiving portion of the element, at least a bottom surface of the culture container being formed of transparent material, a cell cultured in the culture container, and culture medium for growing the cell.
