A non-inverting amplifier includes n external input terminals which receive n (n>=3) input voltage signals having a constant sum of voltages, respectively, n amplification units each including n-1 internal input terminals connected to n-1 terminals of the n external input terminals in a different combination for each of the amplification units, n-1 voltage-to-current converters which convert input voltage signals from the internal input terminals into current signals, and a load which converts an added current signal obtained by adding up the current signals into an output voltage signal, and n external output terminals which output n output voltage signals from the n amplification units.
