An obstacle alarm device, adapted for clearly indicating to a driver the presence of an obstacle approaching a vehicle without making it difficult to see the circumstances of the periphery of the vehicle, comprises: a captured image acquisition unit acquiring a captured image in which an image of a visual scene of a periphery of a vehicle has been captured; an attention-prioritized captured image generation unit generating an attention-prioritized captured image on the basis of the captured image; an object presence determination unit determining whether or not an object is present in a periphery of the vehicle; a movement direction determination unit determining a movement direction of the object; and a clear indication image output unit causing a frame sign, which has a smaller outer shape than an outline of the attention-prioritized captured image and is turned on for a fixed duration of time and thereafter turned off, to be displayed at sequentially varying positions centerward from an outer edge part of the attention-prioritized captured image, and for repeatedly performing such displaying, in a case where the movement direction determination unit has determined that the object is moving toward the center of the attention-prioritized captured image.
