Abstract: To provide an analysis device, analysis method and analysis program which allow a user to easily grasp the junction state of two metal members.SOLUTION: An analysis device analyzes the junction state of two metal members that are joined by application of heat for generating solid-phase diffusion on a junction interface of the two overlapped metal members. The analysis device calculates a value to be given to a variable of a mathematical model expressing the progress speed of the junction of the two metal members on the basis of the junction condition when joining the two metal members (Step S103). The mathematical model includes the temperature and pressing force of a heated portion on the junction interface between the two metal members as a variable. The analysis device calculates the junction rate of the two metal members by giving the value obtained on the basis of the aforementioned junction condition to the variable of the mathematical model read from a storage device (Step S104). The analysis device displays the junction state of the two metal members on a display device on the basis of the calculated junction rate (Step S105).SELECTED DRAWING: Figure 10
