PROBLEM TO BE SOLVED: To provide a measurement device and a measurement method capable of precisely calibrating output power of a signal generator. SOLUTION: The measurement device measuring an output reflection coefficient of a signal generator outputting an output signal of the power according to a given setting value includes: at least four connection circuits having mutually different input reflection coefficients; a selection part sequentially connecting each of the at least four connection circuits to the signal generator; a generation control part by which the output signal of the prescribed power and a prescribed frequency is output from the signal generator; a power measurement device sequentially measuring the power of the output signal output from the signal generator in each of the states in which the at least four connection circuits are sequentially connected to the signal generator; and an output reflection coefficient calculation part calculating the output reflection coefficient of the signal generator on the basis of the prescribed power, a power measurement value measured by the power measurement device, and the input reflection coefficient at each of the prescribed frequencies of the at least four connection circuits.
