A monolithic ceramic electronic component and a method for manufacturing the same are provided, wherein intrusion of a plating solution into a ceramic laminate can be suppressed and prevented so as not to cause deterioration of the insulation resistance and the deterioration of the weather resistance, and satisfactory reliability of electrical connection between an external electrode and internal electrodes and satisfactory solderability of the external electrode are exhibited. A monolithic ceramic electronic component includes a ceramic laminate 1 provided with ceramic layers 3 and internal electrode layers 2 (2a, 2b) disposed between the ceramic layers in such a way that a part of each internal electrode is led to an end surface 4 (4a, 4b) and the external electrode 5 (5a, 5b) disposed on the end surface, to which the internal electrode layers are led, in such a way as to connect to the internal electrode layers. At least one end portion in a longitudinal direction of an exposed portion A of the internal electrode layer led to and exposed at the end surface of the ceramic laminate is covered with a glass film 31, and the internal electrodes and the external electrode are electrically connected to each other at a portion not covered with the glass film in the exposed portion of the internal electrode layer.
