Abstract:
1. A liquid adhesive for electronic components, which contains: a curable compound; a curing agent; and inorganic fine particles, a liquid portion in the liquid adhesive having a solubility parameter (SP value) in the range of 8 to 11, including 8 and not including 11, said inorganic fine particles including a mixture of at least inorganic fine particles (A) and inorganic fine particles (B), the inorganic fine particles (A) having an average primary particle diameter of 50 nm or less and a hydrophobization degree (M value) in the range of 30 to 47, including 30 and 47, and the inorganic fine particles (B) having an average primary particle diameter of 50 nm or less and a hydrophobization degree (M value) of 65 or more, wherein a blending amount of the inorganic fine particles (B) is 30 to 600 parts by weight to 100 parts by weight of the inorganic fine particles (A), and wherein a total content of the inorganic fine particles (A) and the inorganic fine particles (B) is 2 to 20 parts by weight to 100 parts by weight of the curable compound.
