Abstract: In a light flux controlling member (140), light emitted from a light-emitting element enters from an incidence region (141), and is emitted from an emitting region (142). The light-incidence region (141) includes a plurality of protrusions. The protrusions have ridgelines that are connected between two of four virtual lines that are adjacent to each other, the virtual lines joining an intersecting point and a vertex point of diagonal lines of a first virtual quadrangle. Valleys are formed between the plurality of protrusions. The planar shape of the ridge lines is an arc, and the radius of curvature of the ridge lines is greater than the distance from the intersection point of the diagonal lines of the first virtual quadrangle to the midpoint of the ridge lines.

A laminated body assembly kit with an alignment function of the present invention includes a first substrate 10 and a second substrate 20 that are to be laminated together. The first substrate 10 has a lens portion 11 on a surface thereof opposite to a facing surface thereof that faces the second substrate 20. The second substrate 20 has an alignment mark portion 21 on at least one surface thereof. The first substrate 10 and the second substrate 20 respectively have the lens portion 11 and the alignment mark portion 21 such that, in a set laminated state, the alignment mark portion 21 of the second substrate 20 is located at a focal position of the lens portion of the first substrate 10. An image of the alignment mark portion 21 that is formed in the lens portion 11 in the set laminated state is an image indicating that the set laminated state has been achieved.

Abstract: The present invention provides a marker unit that can be easily installed in the same target object under the same installation condition, for example. The marker unit of the present invention includes: an upper substrate; and a lower substrate, wherein the upper substrate is laminated on the lower substrate to form a laminate. The lower substrate has a lower substrate detection target portion exposed to an upper surface side of the laminate on an upper surface thereof, and the lower substrate has at least two positioning portions on a lower surface thereof. The detection target portion is detectable from an upper surface side of the laminate, and each positioning portion is visually recognizable from a side surface direction of the laminate and is visually unrecognizable from the upper surface direction of the laminate. When the laminate is installed in an installation target object, each positioning portion is disposed on the lower substrate at a position corresponding to an alignment mark with the marker unit in the installation target object by recognizing from the side surface direction of the laminate.
