1. the manufacture method of a flat membrane element, it is characterized in that, the diaphragm that will carry out Separation of Solid and Liquid overlaps with the support plate of this diaphragm of supporting, the material of described support plate by laser-transmissible formed, described diaphragm contains mineral-type materials and has laser absorption, shine described laser from described support plate side towards the junction surface of itself and described diaphragm, behind deposited primary diaphragm on the one side of described support plate, the secondary diaphragm of planar dimension greater than described primary diaphragm is configured on the another side of described support plate, so that the junction of described secondary diaphragm and described support plate is in the outside of the end of described primary diaphragm, thus the another side of described secondary diaphragm and described support plate is deposited;

  • Described diaphragm has epidermal area, supporting course and the impregnate layer between them, and it is directly deposited so that described supporting course side is engaged with described support plate to carry out Ear Mucosa Treated by He Ne Laser Irradiation;

    Described epidermal area is made of inorganic material;

    Described supporting course is made of the synthetic resin material that has laser absorption by mixed carbon black;

    Described impregnate layer is to sneak under the state that is impregnated in the described supporting course at the material that consists of described epidermal area to form.
