Abstract: A restricting device for a flexible wiring board includes an insertion portion into which at least both side portions of the flexible wiring board are inserted. The insertion portion includes: a rear restricting portions protruding in a thickness direction of the flexible wiring board; a front restricting portion located forward of the rear restricting portion in an insertion direction; a restricting region formed between the front restricting portion and the rear restricting portion, and an inner restricting portion located further inward than the rear restricting portion with respect to a width direction of the flexible wiring board and protruding in a direction opposite to a protruding direction of the rear restricting portion. The protruding portion passes over the rear restricting portion and is restricted from moving in a front-rear direction in the restricting region while the flexible wiring board is being inserted into the insertion portion.

Abstract: A superficial model with an inner reinforcing structure having communication ports formed for communication among cells defined by ribs constructing a honeycomb structure. For this purpose, a process of temporarily stopping light exposure is added in a light exposure process for modeling ribs. Alternatively, a process of offsetting phases of ribs is added in the light exposure process for modeling ribs.
