Abstract

Provided is a curable resin composition including: (A) cyclic imide resins represented by the following formula (1): <img class="EMIRef" id="d74ae674-f241-435d-bfc4-de2c339d3b80-ia01" /> wherein, in the formula (1), A represents a tetravalent organic group including a cyclic structure, Q is, for example, a divalent aliphatic hydrocarbon group, B represents an arylene group, X represents a hydrogen atom or a methyl group, and n and m are independently 0 to 200; and (B) a curing catalyst, wherein the composition exhibits a minimum complex viscosity at 40 to 150°C of (α) 100 to 10,000 Pa·s (as measured at 1 Hz frequency) and (β) 10 to 2,000 Pa·s (as measured at 2 Hz frequency), and results in a cured product that satisfies (γ) a die shear strength with glass at 25°C of 10 MPa or more, and (δ) a die shear strength with copper at 25°C of 10 MPa or more.
