To provide a walking beam capable of roughly continuously move a substrate without vertically moving the substrate and hardly producing a shadow (cloud) on the substrate.

This walking beam is used to carry the substrate 1 coated with a paste material in a heat treating furnace. This walking beam is constituted of two movable beams 3, 5 to independently drive at a shorter stroke than length of the substrate 1 in the furnace length direction and constitutes its characteristic feature that support pins 7, 9 to support the substrate 1 by making contact with the substrate 1 are provided on each of the movable beams, rising ends of the two movable beams 3, 5 are made to be at the same level and the substrate 1 between the beams is received and delivered on the rising ends.
