PROBLEM TO BE SOLVED: To provide a microchip, particulate dispensing device, and feed flow method for controlling the moving direction of particulates accurately and safely at a high speed, in a flow channel of the microchip that hardly damages the particulates and is sealed. SOLUTION: The microchip 1 includes a liquid flow channel 2 in which liquid containing the particulates flows, and a gas flow channel 3 in which gas such as air, carbon dioxide or inert gas. When a droplet containing the particulates delivered from a liquid flow channel 2 is guided to a branch region 5, gas is not injected from the gas flow channel 3. Only when the droplet is intended to be guided to a branch region 6, the gas is injected towards the liquid containing the particulates from the gas flow channel 3, and the moving direction of the droplet in a cavity 4 is altered.
