A digital camera includes: a camera body provided with an inlet port and an outlet port for a spray gas, the camera body defining a space in a photographic light path; a first passage formed in the camera body to communicate the inlet port and the outlet port, the first passage being provided with a restricted section; and a communication unit that communicates the restricted section of the first passage with the space in the photographic light path in the camera body. When the dust is floating in the space in the photographic light path and the spray gas flows through the first passage, the dust floating in the space is led to the restricted section.
