Patent ID: 8138266

Claim:
A semiconductor-encapsulating resin composition comprising: a compound (A) having two or more glycidyl ether groups; and a compound (B) represented by general formula (6) wherein —Ar 1 — is a group selected from a phenylene group, a 1-napthylene group, a 2-naphthylene group, an oxybiphenylene group, and a biphenylene group; —Ar 2 — is a group selected from a phenylene group, a biphenlyene group, and a naphthylene group; however, the case where both —Ar 1 — and —Ar 2 — are phenylene groups is eliminated; X is a hydrogen atom or an organic group that has 1 to 20 carbon atoms and that may have a hydroxyl group, each of substituents R1 introduced in —Ar 1 — is an organic group having 1 to 20 carbon atoms, and substituents R1 may be the same or different; each of substituents R2 introduced in —Ar 2 — is an alkyl group having 1 to 4 carbon atoms, and substituents R2 may be the same or different; k is an integer in the range of 0 to 7; l is an integer in the range of 0 to 8; and each of the averages of p and q is a positive number more than 0 and less than 10.
