Slide fastener elements, comprising:

• at least one fastener element member made of a synthetic resin;
• a metallic coating layer with a thickness of 0.001 to less than 1.0 .mu.m formed on a surface of the fastener element member so as to give the surface of the fastener element member a metallic luster;
• and
• a finishing coat layer on the metallic coating layer formed of a material selected from the group consisting of a thermosetting, electro radiation curing, and ultraviolet curing synthetic resins.
