Abstract
A resin substrate includes a base portion including one first resin sheet made of a thermoplastic resin as a main material or a stack of two or more first resin sheets each made of a thermoplastic resin as a main material, the base portion including a main surface, and first and second connecting conductors provided on the main surface of the base portion and spaced away from each other. The base portion includes a convex portion separating the first and second connecting conductors on the main surface by a second resin sheet disposed at a position on a surface of the base portion or inside the base portion. The second resin sheet is made of the same material as the first resin sheet.

A resin substrate comprising:
- a base portion including one first resin sheet made of a thermoplastic resin as a main material or a stack of two or more first resin sheets each made of a thermoplastic resin as a main material, the base portion including a main surface;
- and
- a first connecting conductor and a second connecting conductor that are provided on the main surface of the base portion so as to be spaced away from each other;
- wherein
- a portion of each of the first connecting conductor and the second connecting conductor extends below the main surface on which the first connecting conductor and the second connecting conductor are provided;
- the base portion includes a convex portion separating the first connecting conductor and the second connecting conductor from each other on the main surface by a second resin sheet disposed at a position on a surface of the base portion or inside the base portion;
- a material of the second resin sheet is the same as a material of the first resin sheet;
- the convex portion includes a bridge portion and a frame-shaped portion that supports the bridge portion;
- the bridge portion of the convex portion formed by the second resin sheet is disposed so as to entirely or substantially entirely cross and cover a region of the main surface that extends from the first connecting conductor to the second connecting conductor when seen in a cross-sectional view;
- and
- no conductor is provided on the convex portion separating the first connecting conductor and the second connecting conductor.

A method of manufacturing a component-mounted resin substrate, the method comprising:
- preparing a resin substrate, the resin substrate including a base portion formed by one first resin sheet made of a thermoplastic resin as a main material or formed by a stack of two or more first resin sheets each made of a thermoplastic resin as a main material, the base portion including a main surface, the resin substrate including a first connecting conductor and a second connecting conductor that are formed on the main surface of the base portion so as to be spaced away from each other, the base portion including a convex portion separating the first connecting conductor and the second connecting conductor from each other on the main surface by a second resin sheet disposed at a position on a surface of the base portion or inside the base portion, a material of the second resin sheet being the same as a material of the first resin sheet;
- preparing a component including a first external electrode and a second external electrode;
- and
- disposing the component on an upper surface of the base portion such that the convex portion contacts a region between the first external electrode and the second external electrode of the component, and electrically connecting the first connecting conductor and the second connecting conductor to the first external electrode and the second external electrode, respectively;
- wherein
- a portion of each of the first connecting conductor and the second connecting conductor extends below the main surface on which the first connecting conductor and the second connecting conductor are provided;
- the convex portion includes a bridge portion and a frame-shaped portion that supports the bridge portion;
- the bridge portion of the convex portion formed by the second resin sheet is disposed so as to entirely or substantially entirely cross and cover a region of the main surface that extends from the first connecting conductor to the second connecting conductor when seen in a cross-sectional view;
- and
- no conductor is formed on the convex portion separating the first connecting conductor and the second connecting conductor.
