Provided is a high-reliability level shift circuit not prone to faulty operation due to noise. This level shift circuit (1) is provided with: a first and second current control element (12a, 12b) into the control terminals of which a reverse-phase input signal and a same-phase input signal are inputted, respectively; a first and second load circuit (13a, 13b) which are connected at one end to a high side power source terminal (Vb) and at the other end to the first terminals of the first and second current control elements (12a, 12b); a comparator (14) in which a pair of differential input terminals (Np, Nn) connects separately to the first terminals of the first and second current control elements (12a, 12b); a current generating circuit (3) in which first and second current output terminals (Na, Nb) connect to second terminals of the first and second current control elements (12a, 12b) and each of which separately generates a current which flows through the respective first and second current control elements (12a, 12b); and voltage suppressing circuits (15a, 15b) which connect separately or in common to the first and second current output terminals (Na, Nb) and suppress the voltage from increasing in the first and second current output terminals (Na, Nb), respectively.
