To provide an efficient manufacturing method for construction material for making a concrete material layer in which reinforcing bars are adequately arranged adhere to a block material made of cellular concrete closely and integrating them to produce a panel and to provide a concrete structure combining advantages of cellular concrete and reinforced concrete together by the construction material to increase use property.

In this manufacturing method for the concrete construction material, reinforcing bars are adequately arranged on one face or many faces of the block material made of cellular concrete formed in advance, fluid unsolidified concrete material is poured to form the concrete material layer and make them adhere closely and integrate them in order to produce the panel.
