Abstract: There is a method of manufacturing a multilayer wiring board including: alternately stacking wiring layers and insulating layers; stacking a reinforcing sheet on one surface of the resulting multilayer laminate with a soluble adhesive layer therebetween, wherein an unoccupied region without the soluble adhesive layer is provided within a facing area where the reinforcing sheet faces the multilayer laminate; allowing a liquid capable of dissolving the soluble adhesive layer to infiltrate the unoccupied region to dissolve or soften the soluble adhesive layer; and releasing the reinforcing sheet from the multilayer laminate at the soluble adhesive layer.

Abstract: [Problem] To enable three-dimensional measurement with good precision. [Solution] When three-dimensional measurement is to be performed with good precision using SLAM or the like, images of marks M1, M2, M3, M4 must be captured from various directions by a single-lens camera. In the present invention, directions of imaging by a camera are displayed as sectors C1, C2, C3, C4. For example, it is understood that whereas sectors C1 and C4 have a large central angle and imaging therein is performed from a wide range of directions, sectors C2 and C3 have a small central angle and imaging therein is performed from a narrow range of directions. A photographer seeing such a display can perform additional imaging, and images can therefore be obtained from a wide range of directions, and three-dimensional measurement can be performed with good precision.
