Abstract
A thin film capacitor includes an under electrode, a plurality of dielectric body layers and a plurality of internal electrode layers that are alternately laminated on the under electrode, the internal electrode layers respectively including protrusion parts that each protrude from the dielectric body layers viewed in the lamination direction, and connection electrodes to which at least a portion of each of the protrusion parts contacts. Assuming that protrusion amounts of the protrusion parts of the internal electrode layers that are connected to the same connection electrode are regarded as L, a protrusion amount Ln of a protrusion part of nth (n≧2) internal electrode layer from the under electrode side is smaller than another protrusion amount Ln-1 of another protrusion part of (n−1)th internal electrode layer.
