PROBLEM TO BE SOLVED: To provide a semiconductor chip laminate in which a part of an end of an upper layer semiconductor chip protrudes toward a side beyond an end of a lower layer semiconductor chip, connection failure is prevented in an electric connection terminal positioned on a lower part of a protruding portion and deformation of the upper layer semiconductor chip is suppressed. SOLUTION: The semiconductor chip laminate 1 is provided with a substrate or a first semiconductor chip 2 and second and third semiconductor chips 3, 4. At least a part of an end 4a of the third semiconductor chip 4 protrudes toward the side beyond the end 3a of the second semiconductor chip 3. Between an electric connection terminal 2a and the end 3a of the second semiconductor chip 3, a supporting layer 9 is provided so as not to reach the first electric connection terminal 2a between the bottom surface of a protruding portion 4A and the top surface of the substrate or the top surface of the semiconductor chip 2.
