Chip resistor and method for producing same

A chip resistor comprising:

• a resistance member;
• a pair of electrodes;
• a first protective film;
• a second protective film;
• and
• a third protective film,
• wherein the resistance member includes
• a first main surface,
• a second main surface located on a side opposite to the first main surface, and
• a recess that recesses inward from a plane connecting an edge of the first main surface and an edge of the second main surface,
• the pair of electrodes are respectively disposed on both ends of the first main surface of the resistance member, and a direction connecting respective ones of the pair of electrodes is a direction along the edge of the first main surface and the edge of the second main surface,
• the first protective film is disposed on the second main surface of the resistance member,
• the second protective film is disposed on the first main surface of the resistance member and between the pair of electrodes, and
• the third protective film is disposed on the recess of the resistance member.

A method for producing a chip resistor comprising:

• a step of forming a plurality of grooves on a main surface of a sheet-shaped resistance member and a rear surface located on a side opposite to the sheet-shaped resistance member when viewed from the main surface;
• a step of forming a protective member on the main surface of the sheet-shaped resistance member and inside the plurality of grooves in an integrated manner;
• a step of forming a plurality of electrodes between the grooves that are adjacent to each other at uniform intervals, by pasting a resist on the rear surface of the sheet-shaped resistance member, and performing plating on the rear surface of the sheet-shaped resistance member;
• and
• a step of cutting centers of the plurality of grooves and centers of the plurality of electrodes to divide the sheet-shaped resistance member into individual pieces.
