<p>A position detection device for detecting the position of liquid held in a container, a position detection method, and an analysis device. The position detection device (25) has a surface acoustic wave element (27) placed in contact with the container (7) and having sound emission sections (27b-27d) for generating sound waves by an input of electric energy, a measurement section (26) for measuring electrical characteristics of each sound emission section based on electric energy reflected by each sound emission section, and a determination controller (21c) for determining, based on the difference between the electrical characteristics measured by the measurement section, whether liquid is present at the position of each sound emission section.</p> |
