PROBLEM TO BE SOLVED: To provide a portable laser needle which is convenient in carrying, of which the manufacturing cost is low, and which can be easily used. SOLUTION: In a case 1, a rotary type vertically moving utensil 5, which performs a vertically moving action when a button 2 is pressed, is provided. Then, under the vertically moving utensil 5, a drifting utensil 6, which is equipped with a battery 8, a spring 7', a laser beam-generating tip 15, a laser beam-generating element 14, and a converging lens 13 inside, and can vertically slide, is provided. The laser beam-generating tip 15 has two contact terminals 10, and one contact terminal 10 is connected to the battery 8, and the terminal end of the other is projected from the bottom surface of the drifting utensil 6 after inserting a resistor 9. At the center of the bottom surface of the drifting utensil 6, a beam passage 12 is formed in a manner to protrude. Then, to the terminal end of the beam passage 12, a ceramic needle 4, wherein a laser passing hole 11 is formed, is combined. Accompanying a sliding of the drifting utensil 6, the projected contact terminal 10 is attached/detached to/from the internal slope of a lower case 16, and at the same time, the ceramic needle 4 is inserted/removed into/from a projecting hole 17. |
