Provided is a biological tissue collection method capable of preventing damage of a biological tissue and sucking a mm-order large biological tissue. The biological tissue collection method includes the following steps. First, a component is prepared. The component is provided with multiple (n ≥ 2) holes for passing air from a first surface toward a second surface, a wall is formed between the holes, and an end portion of the wall on a first surface side is rounded and formed only of a curved surface. Next, a biological tissue is collected by the holes of the component. The biological tissue has a mm-order dimension of equal to or greater than 0.5 mm and equal to or less than 100 mm in a maximum direction, and contacts the holes on one surface by suction. Upon collection, equal to or greater than 50% and equal to or less than 90% of the area of the biological tissue is taken as as the total area of the collecting holes.
