the rebar truss has:

a first rebar member that is disposed above and spaced apart from a surface of the wood panel and extends linearly along a first direction parallel to a surface of the wood panel;

a second rebar member extending in a second direction perpendicular to the first direction while repeatedly bending in a vertical direction between the first rebar member and the wood panel, the second rebar member having an upper part facing the first rebar member and a lower part facing the wood panel;

a third rebar member that is disposed between the first rebar member and the wood panel and extends linearly along the first direction; and

a fourth rebar member extending in the first direction while repeatedly bending in a vertical direction between the first rebar member and the third rebar member, the fourth rebar member having an upper part facing the first rebar member and a lower part facing the third rebar member,

an upper part of the second rebar member is welded to the first rebar member,

a lower part of the second rebar member is fixed to the wood panel with the adhesive staple,

an upper part of the fourth rebar member is welded to the first rebar member, and

a lower part of the fourth rebar member is welded to the third rebar member.

7. The rebar-equipped lumber form according to claim 3 , characterized in that the rebar truss has:

a first rebar member that is disposed above and spaced apart from a surface of the wood panel and extends linearly along a first direction parallel to a surface of the wood panel;

a second rebar member that is disposed between the first rebar member and the wood panel and extends linearly along the first direction;

a third rebar member extending in the first direction while repeatedly bending in a vertical direction between the first rebar member and the second rebar member, the third rebar member having an upper part facing the first rebar member and a lower part facing the second rebar member; and

a fourth rebar member extending in a second direction perpendicular to the first direction so as to intersect with the first rebar member,
