Chip resistor

An object is to provide a chip resistor in which hot spots can be dispersed and the adverse effects on performance caused by microcracks can also be reduced. A chip resistor includes an insulating substrate, a resistive element, and electrodes. In the resistive element, a first trimming groove and a second trimming groove are formed. A first vertical groove of the first trimming groove and a second vertical groove of the second trimming groove are formed with a spacing in between in an X1-X2 direction. A first horizontal groove of the first trimming groove and a second horizontal groove of the second trimming groove extend in directions approaching each other, and terminal ends of the first horizontal groove and the second horizontal groove are formed to be separated in the X1-X2 direction such that the first horizontal groove and the second horizontal groove do not overlap in a Y1-Y2 direction.
