Abstract
An elastic valve and a microfluidic device including the same are provided. The elastic valve includes a channel dented by external pressure so as to be elastically restituted; and a plurality of channel closing protrusions, which comprise elastomer as a material, which are protruded from at least one inner side surface of the channel toward an opposite inner side surface, and which are separated from each other so as not to interrupt a flow of fluids, wherein, when external pressure is applied in order to dent the channel, the plurality of channel closing protrusions are deformed so as to be elastically restituted, thereby closing the channel.
