Patent ID: 8217275

Claim:
A sealing material comprising at least (a) a heat curable resin component and (b) a hardner for the heat curable resin component, which has: a ΔE/ΔT in a range of from 0.5 MPa/° C. to 6.7 MPa/° C. wherein ΔE/ΔT represents a ratio of change (ΔE) in storage elastic modulus (E) relative to a temperature change (ΔT) when the storage elastic modulus (E) is determined as the temperature is raised within a temperature range including a glass transition point (Tg) of the cured sealing material, wherein the glass transition point (Tg) of the sealing material is in a range from −80° C. to 50° C. after being cured.
