Summary:PROBLEM TO BE SOLVED: To solve a problem wherein a contact area with a shoe bottom effective for anti-slipping gets narrow thereby a frictional force of the shoe bottom on the grating surface gets low to get easily slippery, at the time other than a rain fall time, when an area of a grating surface gets narrow, although a water film is difficult to be formed and a shoe gets difficult to be slipped when the contact area between the grating surface and the shoe bottom gets narrower. SOLUTION: This grating includes a frame 20 and a grating body 30 provided in the frame 20. The grating body 30 has a plurality of main bars 31 juxtaposed with a required interval, and a connecting member for connecting the main bars, and the grating body 30 is fixed onto the frame 20 by the connecting member. Each main bars 31 includes a leg part 32 and a horizontal part 33 molded of a rigid synthetic resin, and an upper face part 34 provided integrally on an upper face of the horizontal part 33 when molded and molded of synthetic resin softer than the rigid synthetic resin.
