A terahertz wave generating element includes a nonlinear optical crystal generating terahertz waves by propagating light, and a coupling member propagating the generated terahertz waves. The coupling member includes a reflecting face reflecting at least part of the generated terahertz waves. The reflecting face is convex in a propagation direction of the generated terahertz waves. An angle at the coupling member side between the reflecting face and the propagation direction of the light is greater than 90 degrees-cos-1(ng/nTHz) but smaller than 90 degrees at a plane including the light propagation direction. ng represents a group refractive index of the nonlinear optical crystal at a wavelength of the light, nTHz the refractive index of the coupling member at a wavelength of the generated terahertz waves. A curvature radius of the reflecting face, in a reflection region reflecting the radius terahertz waves, is smaller the farther downstream in the light propagation direction.

If, when using a stepping motor as a drive source for a shutter device, the stepping motor missteps as a result of load variation, etc., during driving, a drive ring can no longer be rotated and driven at that point, and an exposure operation can no longer be performed. Provided are a shutter device and an imaging device comprising said shutter device, whereby: a motor drives a member to be driven, using an open loop drive mode, in a first interval in which a light-shielding member maintains a closed or open state even if the member to be driven is driven; and, as a result of the member to be driven being driven, the motor drives the member to be driven, using a feedback drive mode, during a second interval in which the light-shielding member moves from the closed state to the open state or from the open state to the closed state.
