Chip resistor

A chip resistor, comprising:

• a substrate;
• a resistive element formed on a surface of the substrate;
• and
• electrodes formed on either side of the resistive element,
• wherein at least a first trimming groove and a second trimming groove are formed in the resistive element,
• wherein a first edge and a second edge of the resistive element face a direction orthogonal to an inter-electrode direction across the electrodes,
• wherein the first trimming groove and the second trimming groove include respective first and second vertical grooves that extend, in the direction orthogonal to the inter-electrode direction, from the first edge of the resistive element toward the second edge of the resistive element, and the first trimming groove and the second trimming groove are bent from the vertical grooves to respectively form first and second horizontal grooves extending in the inter-electrode direction,
• wherein the first vertical groove of the first trimming groove and the second vertical groove of the second trimming groove are formed with a spacing therebetween in the inter-electrode direction,
• wherein the first horizontal groove of the first trimming groove and the 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 separated with respect to the inter-electrode direction such that the first horizontal groove and the second horizontal groove do not overlap in the orthogonal direction, and
• wherein the second trimming groove is formed inside a region enclosed between a first virtual line joining the terminal end of the first horizontal groove of the first trimming groove to an intersection point of the electrode on the side that the terminal end of the first horizontal groove faces and the first edge, a second virtual line joining the terminal end of the first horizontal groove to the first edge in the orthogonal direction, and the first edge.
