PROBLEM TO BE SOLVED: To provide a laser ionization mass spectrometer and a laser ionization mass spectrometry wherein detection sensitivity is improved. SOLUTION: This is the laser ionization mass spectrometer equipped with a vacuum chamber 2, a molecular beam generator 1 to irradiate a molecular beam of a sample into the vacuum chamber 2, a pair of flat mirrors 4, 5 arranged in the vacuum chamber 2, a laser light generator 7 to make laser light 6 incident into the vacuum chamber 2, a pair of electrodes 8, 9 arranged in the vacuum chamber 2 and to accelerate ionized ions, and an ion detector 12 to detect the accelerated ions. In an optical path in which the laser light 6 moves on reflecting positions in the flat mirrors 4, 5 while repeating reflections between the flat mirrors 4, 5, the molecular beam of the sample is laser-ionized.
