description An edge detection device includes: an image capturing mechanism configured to image-capture an edge of an optical joining block; and a control unit configured to control the image capturing mechanism, wherein the control unit: determines, based on image data of the edge, whether a plurality of regions included in the edge have a defective region including a defect or a non-defective region including no defect; determines whether or not first regions which are included in the plurality of regions and is determined to be the non-defective region satisfy a first condition; calculates a first straight line based on the first regions; and determines the first straight line as a position of the edge when the first regions has satisfied a first condition.
