PROBLEM TO BE SOLVED: To provide a high resolution microscope using terahertz waves without requiring introduction of a fluorescence marker into a sample. SOLUTION: A microscope apparatus 11 includes an ultra-short pulse laser generation unit 12 generating an ultra-short pulse laser beam P3, and a terahertz wave generation unit 14 generating a terahertz wave T1. A microscope part 15 multiplexes the terahertz wave T1 and the ultra-short pulse laser beam P3 to apply them to the sample 151, and on the sample 151, detects a signal S, which is formed by a parametric process and includes a componentω3=ω1±ω2 as a sum frequency or a difference frequency of a frequencyω1 of the ultra-short pulse laser beam P3 and a frequencyω2 of the terahertz wave T1. The detected signal S is turned into an image in an image displaying-recording device 16. COPYRIGHT: (C)2011,JPO&INPIT
