PROBLEM TO BE SOLVED: To provide a laminated type balun transformer, having a structure in which the latitude in the adjustment of electrical characteristic is improved and desired electrical characteristics are easily obtained. SOLUTION: At least two sets ofλ/4 strip lines, which are composed of a set of conducting layers, are arranged in a laminated member constituted of dielectric layers and conducting layers. Theλ/4 strip lines of the respective sets are composed of divided strip lines 1a, 2a and 1b, 2b, and 3a, 4a and 3b, 4b which make a plurality of sets. The divided strip lines 1a and 1b, 2a and 2b, 3a and 3b, and 4a and 4b which make divided sets are divided and arranged on different layers and are electrically connected with each other.
