A monolithic ceramic electronic component includes a first internal electrode including a first region extending to a first end surface and having a relatively large dimension in a width direction and a second region located at the side closer to a front end than is the first region and having a relatively small dimension in a width direction, wherein d1>c1+ng (n represents a constant based on the size of the monolithic ceramic electronic component) is satisfied, where the distance from a first end point which is closest in the first region to the first side surface and which is closest to the second end surface to the second end surface is d1, the distance between first and second wraparound portions is g, and the distance between a front end of the second wraparound portion and the second end surface is c1.
