| description | PROBLEM TO BE SOLVED: To provide a chip resistor capable of adjusting a resistance value with high precision. SOLUTION: A plurality of resistance bodies 4a and 4b having different resistance values are electrically connected in series between a pair of electrodes 2 and 3 formed to face each other at both ends on an insulating substrate 1. The resistance value is adjusted by laser trimming with the plurality of resistance bodies with one having a higher resistance value treated first. By laser-trimming the resistance body first whose resistance value is higher with two resistance bodies electrically connected in series, a chip resistor having a target resistance value with higher precision is obtained compared to the case that a single resistance body is trimmed.
