A sample pretreatment device of an aspect of the present invention includes a conveyance mechanism () including a Z-axis guide () that linearly moves in two axes of an X axis and a Y axis and expands/contracts in a Z-axis direction on a table () where a unit that performs each step of pretreatment is arranged. The Z-axis guide () is integrally provided with a liquid handler () and a grip handler () oriented in opposite directions to each other. A side wall of a housing () on the autosampler side is provided with a sample conveyance opening (). When pretreatment of a sample ends, the Z-axis guide () is moved to a position close to the opening () in a state where a gripper () grips a pretreated plate. An arm () enters a housing of the autosampler through the opening () and an opening formed in the autosampler, and sets a plate at a predetermined position. Thus, the sample pretreatment device can eliminate the labor of the worker setting a pretreated sample in the analysis device.
