PROBLEM TO BE SOLVED: To provide a cell-treating device which can efficiently impart at least one of a physical action, a chemical action and a physiologically active action to at least cancer cells contained in a cell dispersion such as blood. SOLUTION: This cell-treating device includes a slit member 100 which has the first surface 101 and the second surface 102 and in which slit-shaped through-holes 10 penetrated from the first surface 101 to the second surface 102 and extended in one direction are formed, wherein each through-hole 10 has a tapered portion 12; the width of the tapered portion 12 on a cross section orthogonal to the one direction is gradually reduced from the first surface 101 to the second surface 102 side, and is smaller than the average diameter of the cancer cells at the end on the second surface 102 side; and a cell dispersion passes from the first surface 101 side to the second surface 102 side through the through-hole 10.
