In an electronic component, each of a distance between a first outer electrode and a third outer electrode along a length direction and a distance between a second outer electrode and the third outer electrode along a length direction is about 8% to about 13% of a dimension of the electronic component along the length direction.

Electronic component and mounting structure of electronic component

A raw ceramic portion is formed on each of first and second lateral surfaces of a raw ceramic body. The raw ceramic portions contain ceramic particles and more of at least one constituent selected from Ba, Mg, Mn, and a rare-earth element between the ceramic particles than the ceramic section of the raw ceramic body in terms of total amount. The raw ceramic body is fired with the raw ceramic portions thereon. In this way, a ceramic electronic component is obtained that has a main body left after the raw ceramic body is fired with the raw ceramic portions thereon.

Method for manufacturing ceramic electronic component, and ceramic electronic component

A first terminal electrode extends from a second principal surface onto first and second side surfaces and a first end surface such as not to reach a first principal surface. A second terminal electrode extends from the second principal surface onto the first and second side surfaces and a second end surface such as not to reach the first principal surface. A third terminal electrode extends from the second principal surface onto the first and second side surfaces such as not to reach the first principal surface.

A method is provided which includes a reaction step of reacting at least titanium oxide, a calcium compound, and barium hydroxide in a slurry solution so as to produce a perovskite-type composite oxide. The perovskite-type composite oxide is represented by (BaCa)TiO, and x is within a range of 0&#x3c;x&#x2266;0.125. In addition, the method provides a perovskite-type composite oxide in which a water-soluble calcium compound is used as the calcium compound, and when the perovskite-type composite oxide is represented by (BaCa)TiO, x is within a range of 0&#x3c;x&#x2266;0.20.

Method for producing perovskite type composite oxide

A particulate subcomponent for a barium titanate dielectric is obtained from a sol in which a rare earth metal compound is dispersed in water. The rare earth metal compound includes a carboxylic acid having at least three carbonyl groups and at least one rare earth metal which can be Sc, Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu so that the molar ratio (carbonyl group/rare earth metal) is in the range of 1.2 to 3. A method of making the sol and a method of using the sol to make a ceramic powder is described.

Water-based rare earth metal compound sol, manufacturing method thereof, and method for manufacturing ceramic powder using the same

A solid-phase method for making a barium titanate powder involves the steps of compounding powdered barium carbonate and powdered titanium oxide and calcining the mixture. The powdered barium carbonate used is needle particles having an aspect ratio of the length of the long axis to the length of the short axis of at least about 2. The powdered barium carbonate preferably has a specific surface area of about 5 m /g or more. The resulting barium titanate powder is finer and homogeneous.
