Recording head, substrate therefor, and recording apparatus

A substrate for a recording-head comprising:

• a plurality of heating elements provided on a base plate for recording;
• a plurality of metal-insulator-metal (MIM) elements each corresponding to each of said plurality of heating elements and each having an insulating layer and a pair of conductors sandwiching said insulating layer;
• a first connecting section provided for individual groups of said plurality of heating elements;
• and
• a second connecting section provided for individual groups of said plurality of MIM elements,
• wherein said first connecting section and said second connecting section are used to perform matrix-driving for each of said plurality of heating elements, thereby performing recording operations.
