Flow channel structure and method for producing lipid particle

Abstract

According to one embodiment, a flow channel structure includes a first flow channel, a second flow channel, a third flow channel, a first merging portion that connects one end of the first flow channel, one end of the second flow channel, and one end of the third flow channel to one another, a fourth flow channel, a fifth flow channel, and a second merging portion that connects the other end of the third flow channel, one side end of the fourth flow channel, and one end of the fifth flow channel to one another. The one end of the first flow channel of the flow channel structure has a first shallow portion shallower than the first merging portion, and the one end of the fourth flow channel has a second shallow portion shallower than the second merging portion.

Dependencies are inferred from the claim text.
