Substrate for image sensor

An image sensor substrate comprising:

• an insulating layer;
• and
• a conductive pattern part disposed on the insulating layer,
• wherein the insulating layer includes:
• a first insulating part;
• and
• a second insulating part disposed surrounding a periphery of the first insulating part and spaced apart from the first insulating part with a first open region interposed therebetween,
• wherein the conductive pattern part includes:
• a first conductive pattern part disposed on the first insulating part;
• a second conductive pattern part disposed on the second insulating part;
• and
• an extension pattern part disposed on the first open region and interconnecting the first and second conductive pattern parts,
• wherein the first open region includes first to fourth corner regions,
• wherein the extension pattern part includes first to fourth bent portion disposed at the first to fourth corner portions, respectively, and
• wherein each of the first to fourth bent portion has a shape that rotates in the same direction at one end connected to the first conductive pattern part, and is bent to be connected to the second conductive pattern part.
