Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a semiconductor device for fingerprint recognition which can be prevented from breaking due to electrostatic discharging from a finger. SOLUTION: On a substrate, plural 1st electrodes 2 which are arranged in matrix and accumulate electric charges and at least one 2nd electrode 2b which is arranged by the 1st electrodes 2 and fixed at a constant potential such as a ground potential or power source potential are formed; and the 1st electrodes 2 are connected to one source drain area of a transistor under gate control to a word line and the other source-drain area of the transistor is connected to a bit line; and plural semiconductor elements for reading out electric charges accumulated in the 1st electrodes 2 are formed below the 1st electrodes 2. Then a wire 2d which fixes the 2nd electrode 2b at the constant potential is formed below the 2nd electrode 2b.
