Abstract
Antenna side through-holes pass through to the internal surfaces of neighboring resonator holes from an antenna side electrode. The antenna side through-holes (transverse holes) have their axes in a direction substantially at a right angle to the axial direction of the resonator holes and on the internal surface of the antenna side through-holes an inner conductor is formed. The transmission side filter and the antenna side electrode of a duplexer are electrically connected through an antenna side through-hole. The reception side filter and the antenna side electrode are also electrically connected through an antenna side through-hole.
