PROBLEM TO BE SOLVED: To enhance the durability of a passenger conveyor by heightening the strength of the footboards of the passenger conveyor formed from resin materials. SOLUTION: The man conveyor includes footboards to be driven along a guide rail, each footboard consisting of a tread plate stamped by people, a riser face plate exposed to the sides of the tread plate, and a base to support the tread plate and riser face plate, wherein the tread plate, the riser face plate, and the base are formed in a single piece through hardening of a molten resin. A composite construction of the riser face plate and the resin as described above allows exerting an anchor effect to lead to enhancement of the strength. If in particular, molten resin is used where surface unevenness exists on that surface of the riser face plate contacting with the resin, no locational coordination is required and also the resin can turn around till the gap, so that cavity is unlikely to be produced under the tread plate.
