A biological information processing device includes a controller programmed to obtain biological information indicating a body condition, and associate different kinds of the biological information with respective specific graphical elements. Each of the respective specific graphical elements constitute a respective specific appearance of a graphical figure, with one of the respective specific graphical elements representing a surface count of a polyhedron which changes in relation to a numerical change in the biological information. The controller is further programmed to set value to the specific graphical element depending on degree of the biological information for at least one specific graphical element associated with the biological information obtained, and generate indicating data of a biological figure on the basis of the value set, the biological figure being an aggregate of the specific graphical elements.
