Manufacturing method for piezoelectric ceramics

A manufacturing method for a piezoelectric ceramics, comprising at least:

• producing granulating powder by adding a binder to barium titanate particles each comprising manganese at 0.04% by mass or more and 0.20% by mass or less in terms of a metal;
• and
• sintering a mixture prepared by adding at least one compound selected from the group consisting of Ba4Ti12O27 particles and Ba6Ti17O40 particles to the granulating powder.
