A non-transitory computer readable recording medium has an estimation model according to one aspect of the present invention recorded thereon, and the estimation model is included in a program to be executed by a computer and outputs output data estimated based on input data received. In response to receiving, as the input data, a change over time in an intensity of energy emitted from a sealing part of an object subjected to a sealing process through bonding, the estimation model estimates at least one of whether sealing of the object is good or whether the sealing of the object is defective and outputs an estimation result as the output data, the change over time being calculated based on an intensity of energy emitted at each of a first time point and a second time point that is later than the first time point.
