To provide a method for manufacturing an article including a base material and a metal sintered body layer formed on a surface of the base material in which both excellent adhesion of the sintered body layer with respect to the base material and excellent conductivity of the sintered body layer reach a sufficiently high level.SOLUTION: A method for manufacturing an article includes: forming a metal particle-containing layer on a surface of a base material by using a composition containing metal particles; and irradiating laser toward the metal particle-containing layer so that the metal particles are sintered to form a metal sintered body layer, in which the metal particles include flaky metal particles whose median size is 4.0 μm or more.SELECTED DRAWING: Figure 3 【課題】基材と、その表面上に形成された金属の焼結体層とを備える物品であって、基材に対する焼結体層の優れた密着性と焼結体層の優れた導電性の両方が十分に高水準である物品の製造方法を提供すること。【解決手段】基材の表面上に、金属粒子を含有する組成物を用いて金属粒子含有層を形成する工程と、金属粒子が焼結して金属の焼結体層が形成されるように、金属粒子含有層に向けてレーザーを照射する工程と、を含み、金属粒子が、メジアン径が４．０μｍ以上であるフレーク状の金属粒子含む、物品の製造方法。【選択図】図３
