Abstract: An object of the present invention is to provide a sample holder that can carry out a series of observations in which a rotational series image at arbitrary angles, namely, from −180° to +180° around the x-axis of an observation region and a rotational series image at arbitrary angles, namely, from −180° to +180° around the y-axis are obtained without taking a sample out of a sample chamber.A sample holder includes a power unit, a power separator, a rotational movement transmission mechanism, and a linear movement transmission mechanism. The power separator separates one movement of the power unit to be distributed to the rotational movement transmission mechanism and the linear movement transmission mechanism. The rotational movement transmission mechanism provides a rotational movement around a second rotational axis. The linear movement transmission mechanism provides a linear movement around the second rotational axis.
