If a person (referred to as "processor" in this Article below) adds labor to another person's movables, the ownership of the processed thing belongs to the owner of the material; provided, however, that if the value derived from the work significantly exceeds the value of the material, the processor acquires ownership of the processed thing.
他人の動産に工作を加えた者（以下この条において「加工者」という。）があるときは、その加工物の所有権は、材料の所有者に帰属する。ただし、工作によって生じた価格が材料の価格を著しく超えるときは、加工者がその加工物の所有権を取得する。
In the cases prescribed in the preceding paragraph, if the processor provides a portion of the materials, the processor acquires ownership of the processed thing only if the value of provided materials added to the value derived from the labor exceeds the value of the other person's materials.
