PROBLEM TO BE SOLVED: To provide a device for synchronously displaying a dot and line of a radiation beam in which adjusting operation that takes time and effort artificially and error of correction can be avoided. SOLUTION: This device includes a laser light source 1 that is connected to a power supply and generates a radiation beam 11, a lens module 2 for receiving the radiation beam 11 of the laser light source 1 and transmitting a light beam 21 of a predetermined width, and a rod lens 30 that has a refraction mirror plane 30 of a predetermined width cut in parallel with the axis on an outer diameter plane and deflects the projection path of the light beam 21 transmitted by the lens module 2 at a preset angle with the refraction mirror plane 30. In this device for synchronously displaying the dot and line of the radiation beam, the light beam 21 is refracted via the rod lens 3 and projected and displayed on an object as a transmitted light beam 22 to form a photoirradiation reference line 31, and the light beam 21 projected on the refraction mirror plane 30 is projected and displayed on the object as a refracted light beam 23 to form a photoirradiation reference dot 32.
