Abstract
A membrane potential change detection device is provided with a reflection interference measurement light source, a holder which holds a transparent member on which cells are mounted, a reflection interference detection camera which images light emitted from the reflection interference measurement light source and reflected from the cells through the transparent member, to generate a reflection interference image, and an analysis unit which calculates a parameter dI about adhesion between the cells and the transparent member from the reflection interference image and detects a change of membrane potential of the cells on the basis of a change of the parameter dI.
