and a collecting portion connected to the grip portion, wherein the collecting portion includes a first surface, a second surface and a third surface that are adjacent to the first surface with the first surface sandwiched therebetween, and a capillary that has openings on the first surface, the second surface and the third surface. ### Claim 2 A sample collection device comprising: a grip portion; and a collecting portion connected to the grip portion, wherein the collecting portion includes a capillary that has openings located at opposite ends thereof and an opening located on a side surface between the opposite ends. ### Claim 3 (depends on 2) The sample collection device according to claim 2, wherein: the collecting portion includes a first surface, and a second surface and a third surface that are adjacent to the first surface with the first surface sandwiched therebetween; and the openings of the capillary at the opposite ends are located on the second surface and the third surface, and the opening of the capillary on the side surface is located on the first surface. ### Claim 4 A sample collection device comprising: a grip portion; and a collecting portion connected to the grip portion, wherein the collecting portion includes a first surface and a capillary having a groove shape provided on the first surface and formed with openings at opposite ends thereof. ### Claim 5 (depends on 4) The sample collection device according to claim 4, wherein: the collecting portion includes a second surface and a third surface that are adjacent to the first surface with the first surface sandwiched therebetween; and the groove shape includes openings on the second surface and the third surface, and includes an opening of the groove shape on the first surface. ### Claim 6 (depends on 1) The sample collection device according to claim 1, wherein the capillary has a U-letter shape on a cross section perpendicular to a longitudinal direction thereof. ### Claim 7 (depends on 1) The sample collection device according to claim 1, wherein the openings located on the second surface and the third surface communicate with each other via the opening located on the first surface. ### Claim 8 (depends on 1) The sample collection device according to claim 1, wherein the capillary is closed in at least a portion of the first surface. ### Claim 9 (depends on 1) The sample collection device according to claim 1, wherein a width W of the openings on the second surface and the third surface parallel to the first surface and a depth D thereof perpendicular to the first surface satisfy 0.9≤W/D≤1.1. ### Claim 10 (depends on 1) The sample collection device according to claim 1, wherein the grip portion extends in a longitudinal direction thereof, and has a polygonal shape on a cross section perpendicular to the longitudinal direction. ### Claim 11 (depends on 10) The sample collection device according to claim 10, wherein the polygonal shape is a pentagonal shape. ### Claim 12 (depends on 1) The sample collection device according to claim 1, wherein an inner wall of the capillary has a depressed portion or a protruding portion parallel to a longitudinal direction. ### Claim 13 (depends on 1) The sample collection device according to claim 1, wherein: the grip portion extends in a longitudinal direction thereof; and a longitudinal direction of the capillary is perpendicular to the longitudinal direction of the grip portion. ### Claim 14 (depends on 13) The sample collection device according to claim 13, wherein the first surface is perpendicular to the longitudinal direction of the grip portion. ### Claim 15 (depends on 14) The sample collection device according to claim 14, wherein the collecting portion further includes: a depressed portion located on the first surface; and a reagent arranged in the depressed portion. ### Claim 16 (depends on 13) The sample collection device according to claim 13, wherein the first surface is non-perpendicular to the longitudinal direction of the grip portion. ### Claim 17 (depends on 16) The sample collection device according to claim 16, wherein the collecting portion further includes: a fourth surface that is perpendicular to the longitudinal direction of the grip portion and is adjacent to the first surface; a depressed portion located on the fourth surface; and a reagent arranged in the depressed portion. ### Claim 18 (depends on 1) A sample preparation apparatus comprising: the sample collection device according to claim 1; a reagent container having an opening and a bottom portion, and including a chamber that is capable of housing the collecting portion by inserting a part of the sample collection device through the opening, and a through hole that connects the bottom portion with an outside; and a stopper that can be inserted into the through hole and includes a first end surface and a second end surface located in a longitudinal direction thereof and a side surface located between the first end surface and the second end surface, wherein the stopper includes a first discharge hole that has an opening in the second end surface and extends in the longitudinal direction, and a second discharge hole that has an opening in the side surface and is connected to the first discharge hole, wherein the stopper is movable between a retain position in which the first surface is located at a bottom of the chamber and a discharge position in which the opening in the side surface is exposed inside the chamber.
