PROBLEM TO BE SOLVED: To provide a method for making a substrate to mount electronic parts that can stabilize the quality without requiring high accuracy to determine the position for a cutting-out punch. SOLUTION: A method for making a substrate 10 on which to mount electronic parts in which a plate-shaped electrode patterns material 60 is provided on the upper surface of ceramic sheet 20 comprising green sheets, the electrode pattern material 60 is divided into a pair of electrode patterns 30 and a narrow groove-shaped space 50 and a cavity 40 adjacent to the electrode patterns 30 are punched. One of the two parallel edge faces 61 and 62 of the electrode pattern material 60 is opened, an recessed section 64 expanding from the bottom toward the opening 63 is formed, and the narrow groove-shaped space 50 is formed from the bottom of the recessed section 64 to the other edge face 62 of the electrode pattern 60.
