A microinjection apparatus is designed to introduce the transfecting material into the transductant by inserting a minute injection needle (11) into the transductant and includes a container position adjuster (1), an imaging device (2), a position determiner (3) and a plurality of transporters (4). The container position adjuster adjusts the position of a container (12) accommodating therein the transductant. The imaging device captures through a lens (2a), an image of an inside of the container, which has been adjusted in position by the container position adjuster. The position determiner determines the position of the transductant from the image obtained by the imaging device. The plurality of the transporters are operable to transport the plural injection needles, individually for each of those injection needles, in dependence on the position information obtained by the position determiner.
