A radiographic apparatus includes a radiation source that irradiates radiation, a first grating unit, a grating pattern unit, a radiological image detector, and a support unit. The radiation irradiated from the radiation source passes through the first grating unit. The grating pattern unit includes a periodic form that has a period which substantially coincides with a pattern period of a radiological image formed by the radiation having passed through the first grating unit. The radiological image detector detects a masked radiological image which is formed by masking the radiological image by the grating pattern unit. The support unit supports the radiation source, the first grating unit, the grating pattern unit and the radiological image detector. The radiation source is attached to the support unit via a vibration-proof member.
