A substrate position detection device includes: an irradiator that irradiates a predetermined range of a substrate with a predetermined light; an imager that takes an image of the predetermined range of the substrate irradiated with the predetermined light; a moving mechanism that causes a relative movement of the imager and the substrate; and a controller that: detects a position of the substrate by sequentially executing to a plurality of recognition objects on the substrate: a moving process of relatively moving the imager to a position corresponding to a predetermined recognition object among the plurality of recognition objects on the substrate; an imaging process of taking an image of the predetermined recognition object under a predetermined imaging condition; and a recognition process of recognizing the predetermined recognition object based on image data obtained by the imaging process.
