PROBLEM TO BE SOLVED: To provide a blackboard for construction which can easily alter a standing-up angle against a ground subject to circumstances of a construction site, etc. SOLUTION: The blackboard for construction comprises a blackboard body 1 and a leg 3 for making the blackboard body stand up. For the blackboard on which the proximal end section of the leg 3 is mounted on a leg mounting section 4, provided in the rear face side of the blackboard body 1, in a turnable state. The above leg mounting section 4 has a plurality of leg mounting sections 41 and 42 for mounting the proximal end section of the leg 3 in a turnable state. Each of the leg mounting sections 41 and 42 has a stopper 41b and 42b which defines a leg turning angle 3 to be a designated angle different from the one of other leg mounting sections in contacting the leg 3 mounted at the leg mounting sections 41 and 42.
