Infrared sensor and imaging apparatus

An infrared sensor comprising:

• a detection substrate that includes a first substrate in which a plurality of infrared detection elements are arranged in a lattice shape and a plurality of first terminals each of which is associated with one of the infrared detection elements are arranged;
• a readout substrate that includes a second substrate in which a plurality of second terminals each of which is associated with one of the plurality of first terminals are arranged and a readout circuit that reads an electrical signal based on infrared light detected by each one of the plurality of infrared detection elements is formed;
• and
• a plurality of bumps that electrically connects each one of the plurality of first terminals to one of the plurality of second terminals associated with the one of the plurality of first terminals, wherein
• at least one of the plurality of first terminals, the plurality of second terminals, or the plurality of bumps is partially arranged at a position between the infrared detection elements that are adjacent in a top view.
