A method for manufacturing a pressure measuring cell, which has a ceramic platform and a ceramic measuring membrane, wherein the measuring membrane is joined with the platform pressure tightly by an active hard solder, or braze, wherein the method includes: providing the platform, the measuring membrane and the active hard solder, or braze, positioning the active hard solder, or braze, between the platform and the measuring membrane; melting the active hard solder, or braze, by irradiating the active hard solder, or braze, by a laser, wherein the irradiating of the active hard solder, or braze, occurs through the measuring membrane; and letting the active hard solder, or braze, solidify by cooling.
