Abstract

A molding resin composition includes: an epoxy resin; a curing agent; and an inorganic filler containing at least one selected from the group consisting of calcium titanate particles and strontium titanate particles, in which a total content of the calcium titanate particles and the strontium titanate particles is 60% by volume to 80% by volume with respect to a total amount of the inorganic filler.

Claims (26)

1 . A molding resin composition comprising:

an epoxy resin;

a curing agent; and

an inorganic filler containing at least one selected from the group consisting of calcium titanate particles and strontium titanate particles,

wherein a total content of the calcium titanate particles and the strontium titanate particles is 60% by volume to 80% by volume with respect to a total amount of the inorganic filler.

2 . The molding resin composition according to claim 1 ,

wherein the total content of the calcium titanate particles and the strontium titanate particles is 65% by volume to or more with respect to the total amount of the inorganic filler.

3 . The molding resin composition according to claim 1 ,

wherein the inorganic filler contains calcium titanate particles, and

wherein the content of the calcium titanate particles is 60% by volume to 80% by volume with respect to the total amount of the inorganic filler.

4 . The molding resin composition according to claim 1 ,

wherein the curing agent includes an active ester compound.

5 . The molding resin composition according to claim 1 ,

wherein the inorganic filler further contains at least one selected from the group consisting of silica particles and alumina particles.

6 . The molding resin composition according to claim 1 ,

wherein a relative dielectric constant of the total amount of the inorganic filler at 10 GHz is 80 or less.

7 . The molding resin composition according to claim 1 ,

wherein a content of the total amount of the inorganic filler is 40% by volume to 85% by volume with respect to the entire molding resin composition.

8 . The molding resin composition according to claim 1 , which is used in a high frequency device.

9 . The molding resin composition according to claim 1 , which is used in an antenna-in-package.

10 . An electronic component device comprising:

a support member;

an electronic component placed on the support member; and

a cured product of the molding resin composition according to claim 1 which seals the electronic component.

11 . The electronic component device according to claim 10 ,

wherein the electronic component includes an antenna.
