In a three-dimensional model design assistance system in which design rules are registered in advance, it is difficult to manually input all of an enormous number of device placement rules including the distances and directions between respective devices in a design. Information relating to the relative distances and relative directions between respective devices included in performance CAD data is extracted. With respect to each of the extracted relative distances and relative directions in a plurality of cases, a correlation with a performance requirement specification value, and a placement priority are calculated and held as device placement rules. At design time, requirement specifications are inputted, accessory devices are determined, and thereafter the devices are placed according to placement priorities on CAD on the basis of the device placement rules.

To obtain a laser light source module, a copper-based material is press-fitted into a through hole formed in a stem made of an iron-based material, thereby forming a first heat sink. A mount made of a copper-based material is fixed to the first heat sink and at least one semiconductor laser device is mounted on the mount. A second heat sink is bonded to lower surfaces of the stem and the first heat sink by a thermal conductive adhesive. An upper surface of the first heat sink is located on a same plane as that of the stem, and a lower surface of the first heat sink is located higher than that of the stem.
