A design support apparatus that outputs a plurality of pairs of output parameters for a pair of input parameters is provided. The apparatus includes: an analysis controlling unit that generates a sampling point in design space based on an input parameter, performs calculation in accordance with the sampling point, and acquires a calculation result as an output parameter; a machine learning unit that performs machine learning on a relationship between the input and output parameters; a design plan generating unit that calculates a design plan corresponding to information learned by the machine learning unit; a visualizing unit that visualizes the design space, and displays the calculation result and the design plan in the visualized design space; a design region unit that specifies a region in a vicinity of the design plan in the visualized design space; and an output unit that outputs the calculation result contained in the region.
