A distribution analysis device analyzes a distribution of a field having a property satisfying the Laplace equation, and includes: an obtainment unit that obtains measurement data indicating the distribution of the field measured through a sensor sensing area, the sensor sensing area being an area that moves in a measurement area where the distribution of the field is measured and being an area in which the field is sensed as an aggregate; and a calculation unit that calculates analysis data indicating the distribution of the field with a higher resolution than the measurement data, using an arithmetic expression that is obtained by deriving a solution of the Laplace equation using a boundary condition that an integral of the solution of the Laplace equation in a finite interval corresponding to a size of the sensor sensing area matches the measurement data.
