PROBLEM TO BE SOLVED: To provide a moisture measuring device measuring always accurately the amount of moisture contained in coal, and to provide a drying device. SOLUTION: The moisture measuring device 1 for measuring amount of moisture contained in solid fuel includes a Raman scattered light measuring unit 4 for measuring Raman scattered light by irradiating the solid fuel with measuring light; at least one of a dielectric constant measuring unit 2 that measures the amount of moisture contained in the solid fuel based on the dielectric constant of the solid fuel, and a microwave measuring unit 3 for measuring the amount of moisture contained in the solid fuel by measuring the microwave transmitted through the solid fuel, by irradiating the solid fuel with the microwave; and a correction unit 5 for correcting the amount of moisture contained in the solid fuel measured by at least one of the dielectric constant measuring unit 2 and the microwave measuring unit 3, by using the measured result by the Raman scattered light measuring unit 4.
