A resin sheet for circuit member connection used for electrically connecting electrodes facing each other, which are interposed between mutually opposing electrodes, wherein a material constituting the resin sheet has a melt viscosity at 90 DEG C before curing of 1.0 x 10 < 0 to 5.0 x 10 < 5 > Pa s, and the average linear expansion coefficient of the cured product at 0 to 130 ° C is 45 ppm or less. According to the resin sheet for circuit member connection, when the circuit members are connected to each other, the connection resistance at the connection portion does not change much, and the resin sheet has high reliability. |
