Provided is an exposure apparatus that exposes a pattern on a sample, the exposure apparatus including a plurality of blanking electrodes that are provided corresponding to a plurality of charged particle beams and each switch whether the corresponding particle beam irradiates the sample according to an input voltage; an irradiation control section that outputs switching signals for switching blanking voltages supplied respectively to the blanking electrodes; and a measuring section that, for each blanking electrode, measures a delay amount that is from when the switching signal changes to when the blanking voltage changes. |
