Abstract
The present invention provides an apparatus for applying electrical stimulation to cells in a liquid culture medium without using electrodes immersed in the liquid culture medium. This apparatus is an electrical stimulation apparatus A for electrically stimulating cells in a liquid culture medium (2). A liquid culture medium vessel (3) includes: a ring-shaped recess (7) for holding the liquid culture medium (2); and a through hole (6) formed within the ring-shaped recess (7). A magnetic core (1) is made of a magnetic material and disposed such that a portion thereof is inserted through the through hole (6) of the liquid culture medium vessel (3). An excitation coil (5) is wound around the magnetic core (1). A coil power supply (8) supplies a varying current to the excitation coil (5).
