A laser verticality/horizon indicator for construction is provided that realizes irradiation of laser beam, and indication of both a vertical point and a horizontal line using optical refraction. The laser verticality/horizon indicator embodies a scientific and systematic use mechanism through electrically controlled operation of equipment to indicate vertical and horizontal positions as a precise measurement, and to enhance the handling efficiency of the equipment. The laser verticality/horizon indicator includes a mounting board having a driving motor, a rotary bulb, a prism mounted in the rotary bulb, a battery receiving bulb used as a power supply, and a laser inducing hole. The laser verticality/horizon indicator further includes a laser generator separately mounted on the mounting board, and a plumb bob forming a body structure of the verticality/horizon indicator, the mounting board and the laser generator being installed in the plumb bob.
