A bicycle disc brake caliper is basically provided with a first side caliper part, a second side caliper part, a layer of bonding material, a mating recess and a mating protrusion. The first side caliper part includes a first bonding surface. The second side caliper part includes a second bonding surface. The layer of bonding material is disposed between the first and second bonding surfaces of the first and second side caliper parts. The mating recess is disposed on one of the first and second side caliper parts. The mating protrusion is disposed on the other of the first and second side caliper parts and mated with the mating recess. The first and second bonding surfaces of the first and second side caliper parts are fixedly bonded together by the layer of bonding material with a brake disc slot being defined between the first and second side caliper parts.
