The invention relates to a novel delay element, which relates to a structure of the delay element and a powder packaging and producing process. Glue is added into delay powder so that the delay powder is made into paste which can be applied into a groove on a plastic strip, the plastic strip is adhered with another plastic strip after the paste is dried, and accordingly, the delay element body is formed. The delay powder in the delay element body is uniform in density, stable in burning and fine in delay accuracy. Lead is omitted, so that lead pollution is avoided. The novel delay element is simple in manufacturing process, low in cost, can be used for millisecond, half-second and one-second delay detonators and delay devices in fireworks, fire or cartridges.
