Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a device for generating positrons that economically and stably generates the positrons at low energy level. SOLUTION: A main component of the device is constituted of an icosolid aggregate made by combining hollow icositetrahedrons (icosolid elements) which are specially shaped three-dimensional objects and are used as the base of the aggregate. On this occasion, a positron irradiation space is formed in the center by utilizing the special geometry of the hollow icositetrahedrons (icosolid elements), the icosolid aggregate is joined to a lead wire on the anode (+) side of a direct-current (DC) power supply and the end of the aggregate is earthed without any wire connection with a lead wire on the cathode (-) side of the DC power supply to generate positrons and irradiate an object with them in the positron irradiation space.
