PROBLEM TO BE SOLVED: To provide a concrete member capable of preventing the breakages and damage of an electric equipment box on the way of transportation of a precast concrete slab (a half precast slab). SOLUTION: The precast concrete slab 1 manufactured at a plant is so buried that a box subsidiary member 4 such as a depth of plastering cover and a box spliced frame or the like is not projected from the upper surface of the precast concrete slab 1. In site work, after the electric equipment box 6 has been mounted to the box subsidiary member 4 through a coupling means 5, when concrete is placed on the upper surface of the precast concrete slab 1, the precast concrete slab 1 is combined with a concrete layer 7, and a slab or a wall surface or the like can be formed in a state where the electric equipment box 6 is buried.
