PROBLEM TO BE SOLVED: To provide a semiconductor module that can suppress abrupt temperature rise of a semiconductor element. SOLUTION: This semiconductor module has the semiconductor element 11, provided on a metal substrate 15 via an insulating substrate 13 and a heat accumulator 17, and the accumulator 17 is positioned immediately above and in the vicinity of the element 11, temporarily absorbs the heat of the element 11, by causing a phase change from a solid to a liquid at a temperature slightly lower than the workable upper limit temperature of the element 11, and radiates the heat thereafter. |
