A sample processing method may include: removing a liquid component in a container housing a suspension containing a magnetic particle bound with an analyte, while causing magnetic adhesion of the magnetic particle in the container; discharging an elution liquid for releasing the analyte from the magnetic particle from a pipette into the container from which the liquid component has been removed so as to mix the magnetic particle and the elution liquid; moving, after discharging the elution liquid into the container, the pipette relative to and close to an inner wall of the container so as to collect a droplet attached to the inner wall onto an outer surface of the pipette; and moving a tip of the pipette to an accumulation area in which the elution liquid accumulates in the container so as to move the droplet collected on the outer surface of the pipette to the accumulation area.
