The invention relates to a glass manufacturing method and a glass manufacturing apparatus. Provided is a technique for measuring the distance between a glass ribbon and an object. The glass production method has the following (A) to (D). (A) A band-plate-shaped glass ribbon is conveyed at a distance from an object. And (B) capturing a real image of one end of the object facing the glass ribbon and a mirror image of the one end of the object reflected on the glass ribbon with a camera. And (C) measuring the distance between the real image and the mirror image of the captured image. And (D) calculating the distance between the glass ribbon and the object according to the distance between the real image and the mirror image shown in the image.
