1. A power source device utilizing radioactive energy due to α-decay which comprises
a connected structure in which each one of ends of a first metal and a second metal each comprising a structure having one-end and an other end and comprising different kinds of metals suitable for generating Seebeck effect is connected in a conductive state through a one-end bonding part in which uranium (U) and thorium (Th) are supported on a carrier made of boron (B), and an other end side bonding part is connected in a conductive state through a bonding part at the other end in which uranium (U) and thorium (Th) are supported on a carrier made of carbon (C),
the one-end side bonding part in which uranium (U) and thorium (Th) are supported on the carrier made of boron (B) is formed so that it is generated heat by α-decay of uranium (U) and thorium (Th) to raise the temperature to a first temperature,
the other end side bonding part in which uranium (U) and thorium (Th) are supported on the carrier made of carbon (C) is formed so that it is generated heat by α-decay of uranium (U) and thorium (Th) to raise the temperature to a second temperature which is different from the first temperature,
the first metal is provided with a first output terminal part, the second metal is provided with a second output terminal part which is different from the first output terminal part, and
the power source device is a structure capable of outputting a current generated by the Seebeck effect based on a relative temperature difference through the one-end side bonding part that has risen to the first temperature and the other end side bonding part that has risen to the second temperature as an atomic induced voltage power source device through the first output terminal part and the second output terminal part.
