A layer-built capacitor capable of enhancing the ESR without adding other parts (21). First and second internal electrodes (30 and 31) confronting each other to form electrostatic capacities comprise capacity forming portions (34 and 37) functioning to form electrostatic capacities, a terminal connection portion (35) to be connected with a corresponding external terminal electrode (32), and a drawing portion (36) for connecting the capacity forming portions (34 and 37) and the terminal connection portion (35). The drawing portion (36) is not only made narrower than the individual widths of the capacity forming portions (34 and 37) and the terminal connection portion (35) but also curved in the thick direction so as to enlarge an effective length. Condensateur à couches capable d'améliorer la résistance série équivalente sans nécessiter d'autres composants (21). Des première et deuxième électrodes (30 et 31) en regard l'une de l'autre pour former des capacités électrostatiques comprennent des portions formant capacités (34 et 37) fonctionnant pour former des capacités électrostatiques, une portion de connexion terminale (35) destinée à être connectée à une électrode terminale externe correspondante (32), et une portion de tirage (36) pour connecter les portions formant capacités (34 et 37) et la portion de connexion terminale (35). La portion de tirage (36) est non seulement plus étroite que les largeurs individuelles des portions formant capacités (34 et 37) et la portion de connexion terminale (35) mais elle est également incurvée dans la direction épaisse afin d'élargir la longueur efficace.
