Abstract

There is provided a circuit module, including: a circuit substrate including a mount surface; a mounting component mounted on the mount surface; a sealing body that is formed on the mount surface, covers the mounting component, and includes a trench formed from a main surface of the sealing body toward the mount surface, the trench including a first trench portion extending in one of a parallel direction and an orthogonal direction with respect to a direction parallel to the main surface and a second trench portion that is connected to the first trench portion, is parallel to the main surface, and extends in a direction that is not parallel nor orthogonal to the first trench portion; and a shield that covers the sealing body and includes an inner shield portion formed inside the trench and an outer shield portion provided on the main surface and the inner shield portion.

Claims (13)

1. A circuit module, comprising:

a circuit substrate including a mount surface;

a mounting component mounted on the mount surface;

a sealing body that is formed on the mount surface, covers the mounting component, and includes a trench formed from a main surface of the sealing body toward the mount surface, the trench including a first trench portion extending in one of a parallel direction and an orthogonal direction with respect to a direction parallel to the main surface and a second trench portion that is connected to the first trench portion, is parallel to the main surface, and extends in a direction that is not parallel nor orthogonal to the first trench portion; and

a shield that covers the sealing body and includes an inner shield portion formed inside the trench and an outer shield portion provided on the main surface and the inner shield portion,

wherein a surface layer conductor is provided along the trench on the mount surface, and

the trench reaches the surface layer conductor.

2. The circuit module according to claim 1 ,

wherein the trench includes a plurality of first trench portions provided apart from each other, and

wherein the second trench portion connects a gap between the plurality of first trench portions.

3. The circuit module according to claim 1 ,

wherein the mounting component includes a plurality of mounting components, and

wherein the trench is formed to separate the plurality of mounting components.
