A plasma generation system comprising: a base; a conveyance device, said conveyance device comprising a holding device and a pair of conveyor belts arranged on the base so as to be parallel to each other and to extend in a first direction, wherein the conveyor belts are configured to support and convey a loading plate, on which a target object can be loaded, in the first direction, an emitting head, said emitting head comprising a reaction chamber, electrodes (74, 76) provided in said reaction chamber, and an emission port, the emitting head being configured to generate plasma gas by supplying power to the electrodes (74, 76) and by converting a processing gas into said plasma gas, the emitting head being further configured to emit said plasma gas through the emission port and to apply the plasma gas through said emission port to said target object; and characterised by a moving device, said moving device including a beam section and a slider, said beam section being mounted on the base and arranged over the conveyor belts, said slider being slidably held on a side surface of the beam section so as to be slidable in a second direction, which is a horizontal direction perpendicular to the first direction; and by a temperature sensor, said temperature sensor being arranged at an end section of the base in the second direction at a position separated from said emission port, said temperature sensor being configured to detect a temperature of the plasma gas and to output a detection signal corresponding to the detected temperature, wherein the emission port is configured to emit the plasma gas to the temperature sensor, and said emitting head is mounted on a side surface of the slider so as to be movable in the second direction above the base between a position above the temperature sensor and a position above the target object. a base;
