A modular fluidic chip includes a body configured to have at least one flow channel formed in an inside thereof and be connected to another modular fluidic chip to allow the at least one flow channel to communicate with a flow channel provided in the other modular fluidic chip. A fluidic chip capable of performing one function is formed in the form of a module, whereby a fluidic flow system of various structures can be implemented without restriction in shape or size by connecting a plurality of fluidic chips capable of performing different functions as necessary. Through this, various and accurate experimental data can be obtained, and when a specific portion is deformed or damaged, only the fluidic chip corresponding thereto can be replaced, thereby reducing manufacture and maintenance costs.
