PROBLEM TO BE SOLVED: To provide a simple, inexpensive and easily placeable/recoverable temperature-sensitive snow depth meter having high measurement accuracy both in a snow deposition period and in a snow melting period, and to provide its measuring method. SOLUTION: In a period (snow deposition period) until reaching the deepest snow quantity, the mean value between a measured value measured by a one-strut type measuring part 100 comprising one strut 102 on which a plurality of thermometers 101 are arranged vertically at equal intervals and a measured value measured by a many-strut type measuring part 200 formed by arraying each one thermometer 201 at the same height as each height of the thermometers 101 respectively, on each upper end of a plurality of struts 202 having each different height is used as a measured value of the snow depth, and in a period (snow melting period) after reaching the deepest snow quantity, a measured value only by the many-strut type measuring part 200 is used as the measured value of the snow depth.
