Abstract: In a transmission line, a thickness of a second section is smaller than that of a first section and of a third section. A center of the second section is above a center of the first section and a center of the third section in a laminated body up-down direction. A distance between a second signal conductor layer and a neutral plane of the second section is shorter than a distance between a first signal conductor layer and a neutral plane of the second section and a distance between a third signal conductor layer and a neutral plane of the second section in the laminated body up-down direction. A length of the second signal conductor layer between first and second interlayer connection conductors is equal to or less than about ½ of a wavelength of a high-frequency signal transmitted by the transmission line.

Abstract: A multilayer electronic component includes a multilayer body including dielectric layers and inner electrode layers, the multilayer body including an electrode facing portion in which the inner electrode layers are laminated to face each other with the dielectric layers interposed therebetween. The multilayer body has a thickness of at least about 1.5 mm in a lamination direction, a length of at least about 3.0 mm, and a width of at least about 1.5 mm. Each of the dielectric layers includes Ba, Ti, and Cl. A Cl concentration C1 in the entire electrode facing portion satisfies about 10 wtppm≤C1≤about 50 wtppm. On an imaginary central axis line, a Cl concentration C2 in a central portion of the electrode facing portion and a Cl concentration C3 in both end portions of the electrode facing portion satisfy about 0.5C2≤C3
