Abstract
The object of the present invention is to provide a technic for accurately measuring a connection state between a flexible board and a circuit board. A measurement apparatus includes a flexible board connected to a plurality of electrode terminals in a state of being superimposed on the plurality of electrode terminals provided on a circuit board, and a laser displacement meter configured to measure a height distribution of a surface of a connection portion of the plurality of electrode terminals of the circuit board. The plurality of electrode terminals are linearly arranged at a predetermined pitch, and the laser displacement meter is configured to continuously measure a height position of the surface of the connection portion while scanning from one side to an other side in an arrangement direction of the plurality of linearly arranged electrode terminals.
