Abstract

A multilayer electronic component may include a multilayer body including a plurality of magnetic material layers, and an internal electrode disposed in the multilayer body. The internal electrode may contain a conductive metal and glass, and the glass contains a vanadium (V) oxide. Also, a conductive paste composition for an internal electrode includes a conductive metal and glass, wherein the glass contains a vanadium (V) oxide.

First claim

What is claimed is:

1. A conductive paste composition for an electrode, comprising:
a conductive metal and glass,
wherein the glass contains a vanadium (V) oxide,
one or more selected from a group consisting of a silicon (Si) oxide and a boron (B) oxide;
one or more selected from a group consisting of a lithium (Li) oxide, a potassium (K) oxide, and a calcium (Ca) oxide; and
one or more selected from a group consisting of a titanium (Ti) oxide and an aluminum (Al) oxide.

2. The conductive paste composition for an electrode of claim 1 , wherein when a molar ratio of one or more selected from the group consisting of the silicon (Si) oxide and the boron (B) oxide is defined as a, a molar ratio of one or more selected from the group consisting of the lithium (Li) oxide, the potassium (K) oxide, and the calcium (Ca) oxide is defined as b, a molar ratio of the vanadium (V) oxide is defined as c, and a molar ratio of one or more selected from the group consisting of the titanium (Ti) oxide and the aluminum (Al) oxide is defined as d, a, b, c, and d satisfy a+b+c+d=100 mol %, 30 mol %≦a≦60 mol %, 10 mol %≦b≦30 mol %, 10 mol %≦c≦30 mol %, and 1 mol %≦d≦20 mol %.

3. The conductive paste composition for an electrode of claim 1 , wherein a content of the glass ranges from 0.1 to 1 wt %.

4. The conductive paste composition for an electrode of claim 1 , wherein a weight ratio of the vanadium (V) oxide with respect to the conductive metal is in a range of 0.00025 to 0.00500.

5. The conductive paste composition for an electrode of claim 1 , wherein the conductive metal comprises one or more selected from a group consisting of silver (Ag), palladium (Pd), aluminum (Al), nickel (Ni), titanium (Ti), gold (Au), copper (Cu), and platinum (Pt).
