Claim 0:
1. A particle separation device comprising:
a straight main flow path inside a plate-like base body, the straight main flow path including a flow outlet opened in at least one of an upper surface and a lower surface of the base body;
a plurality of branch flow paths connected to a portion midway through a side surface of the straight main flow path in a direction perpendicular to the side surface, and a flow inlet opened in at least one of the upper surface and the lower surface of the base body,
the flow inlet comprising
a sample flow inlet through which a sample which is a fluid containing particles to be separated flows toward the straight main flow path; and
a pressing flow inlet connected to a side surface of the straight main flow path located on an upstream side and opposite to the plurality of branch flow paths in a direction perpendicular to the side surface of the main flow path, said pressing flow inlet configured to press the sample flowing in the straight main flow path against a side of the at least one of the branch flow paths, wherein in a planar view of the base body, the sample flow inlet is connected to the main flow path via an R-shaped first bending part, a first straight part, an R-shaped second bending part, and a second straight part, and a width in the first bending part and a width in the first straight part are larger than a width in the second bending part and a width in the second straight part, and the width in the second bending part and the width of the second straight part are larger than a width in the straight main flow path; and the pressing flow inlet is connected to the side surface of the straight main flow path via a third straight part, an R-shaped third bending part, a fourth straight part, and a fifth straight part, and a width in the third straight part is larger than a width in the fourth straight part, and the width in the fourth straight part is larger than a width in the fifth straight part.
