A substrate has a base, an intermediate layer, a conductive layer, and conductive films. The base is a ceramic insulator. The intermediate layer is on a main surface of the base. The conductive layer is on the intermediate layer. The conductive films are on the conductive layer, covering an exposed portion of the conductive layer.

Substrate

A tread unit of a passenger conveyor includes: a tread, a tread reinforcing member and a riser which are made of fiber reinforced plastic made by knitting fibers together. The surfaces of the cleat portions of the tread and the riser are provided with surface treated layers in which the wear resistance and coefficient of friction are controlled. As a result of this construction, the aesthetic design of the tread unit and of the passenger conveyor system can be improved. In addition, the reduced weight of the tread unit contributes to labor-saving at the time of mounting, and a passenger conveyor system using these tread units can be reduced in size and weight as a whole.
