A temperature estimation device (10) includes: a temperature measuring unit that measures surface temperatures of a plurality of different positions in a controller (20) controlling an operation of a drive source (30); and an estimation unit that estimates at least one of an outside air temperature in the vicinity of the controller (20) and an elapsed time between when the controller (20) is stopped and when the controller (20) starts to operate again based on the surface temperatures of the plurality of positions that are measured by the temperature measuring unit (10) when the controller (20) is stopped and when the controller (20) starts to operate again and respective thermal time constants (τ1, τ2) that indicate how easily heat is dissipated from the plurality of positions respectively.
