A heat-sensitive recording head including an insulating substrate, an array of heat generating elements, a plurality of leads alternately arranged on both sides of the array of heat generating elements on the insulating substrate with the heat generating elements interposed between the leads. Lead wires are connected to predetermined ones of the leads either directly or through diodes. The lead wires are arranged in a matrix format and heat generating elements are coupled in blocks with the number of blocks being equal to half the number of common drive terminals provided. With the number of blocks represented by n, the average value of the resistances of the heat generating elements by r, and the maximum variation of the resistances by +/-r, <IMAGE> is established.
