A shape measuring device comprising: a pattern display member having a predetermined pattern disposed on one side or the other side facing a measurement object which is a transparent flat plate, the pattern display member being configured to form an image of the predetermined pattern on a front face and back face of the measurement object; an image pick-up section that is configured such that respective reflected images of the predetermined pattern on a front face and back face of the measurement object is separated in a separation direction perpendicular to an extension direction of the predetermined pattern, the image pick-up section being configured to capture the reflected images of the predetermined pattern on the front face and back face of the measurement object to thereby generate an image including the respective reflected images on the front face and back face; a calculating section that is configured to calculate an inclination angle of at least the front face or the back face from the reflected images captured by the image pick-up section on the basis of a positional relation between the measurement object, the predetermined pattern and the image pick-up section; and a determining section that is configured to determine a shape of at least the front face or the back face on the basis of the inclination angle calculated, wherein the predetermined pattern includes a plurality of elements, and one end and the other end of each element of the plurality of elements, which are formed in a direction perpendicular to the extension direction, are deviated from each other in the extension direction, and wherein the predetermined pattern is a zigzag line, or a zigzag line formed of blocks arranged at intervals, or a pattern formed into a sine wave shape by the plurality of elements. a pattern display member having a predetermined pattern disposed on one side or the other side facing a measurement object which is a transparent flat plate, the pattern display member being configured to form an image of the predetermined pattern on a front face and back face of the measurement object; an image pick-up section that is configured such that respective reflected images of the predetermined pattern on a front face and back face of the measurement object is separated in a separation direction perpendicular to an extension direction of the predetermined pattern, the image pick-up section being configured to capture the reflected images of the predetermined pattern on the front face and back face of the measurement object to thereby generate an image including the respective reflected images on the front face and back face; a calculating section that is configured to calculate an inclination angle of at least the front face or the back face from the reflected images captured by the image pick-up section on the basis of a positional relation between the measurement object, the predetermined pattern and the image pick-up section; and a determining section that is configured to determine a shape of at least the front face or the back face on the basis of the inclination angle calculated, wherein the predetermined pattern includes a plurality of elements, and one end and the other end of each element of the plurality of elements, which are formed in a direction perpendicular to the extension direction, are deviated from each other in the extension direction, and wherein the predetermined pattern is a zigzag line, or a zigzag line formed of blocks arranged at intervals, or a pattern formed into a sine wave shape by the plurality of elements.
