摘要： The present invention provides a cell stimulation device capable of uniformly electrically stimulating cells intended to be electrically stimulated, and of preventing medium components from decomposing and depositing.
[Solution] The cell stimulation device according to the present invention is intended to stimulate the cells being cultured in a culture medium, and is characterized in that the cell stimulation device includes an electron emission element for feeding electric charges to the culture medium via a gas phase, and an electric charge collecting electrode for collecting the electric charges from the culture medium, the electron emission element includes a lower electrode, a surface electrode, and an intermediate layer disposed between the lower electrode and the surface electrode, and the electric charge collecting electrode is disposed so as to be contactable with the culture medium.
