A chip resistor including, a substrate having a main surface, a first resistance circuit formed at the main surface of the substrate, a second resistance circuit formed at the main surface of the substrate apart from the first resistance circuit, a common internal electrode formed at the main surface of the substrate and electrically connected to the first resistance circuit and the second resistance circuit, a first internal electrode formed at the main surface of the substrate and electrically connected to the first resistance circuit, a second internal electrode formed at the main surface of the substrate and electrically connected to the second resistance circuit, and a dummy resistance circuit formed in a region between the first resistance circuit and the second resistance circuit at the main surface of the substrate so as to be in an electrically floating state.
