PROBLEM TO BE SOLVED: To generate low energy neutrinos with a simple and low cost device so as to be detected, and to perform a neutrino communication by making use of them and to observe the solar neutrinos. SOLUTION: Three stages of layers in each of which a sheet of thin paper moistened with a salt solution is sandwiched between a wide copper plate and a wide aluminum plate are stacked so as to form a Voltaic pile (a first Voltaic pile). A weak magnetic field which is parallel to its surface is applied by using a solenoid coil which is wound around it. Then, another Voltaic pile (a second Voltaic pile) to which no magnetic field is applied is formed in the same manner as the first Voltaic pile. The first Voltaic pile and the second Voltaic pile face each other, and a distance between both faces is increased. Thereby, when the first Voltaic pile is discharged, neutrinos are generated. The generation of an increment in the electric discharge of the second Voltaic pile is read out by a galvanometer.
